Kids March for a ‘Walkable’ School

  • Parents and students at Monee Elementary take over the road that leads to the school. They hope to raise awareness about an unfinished sidewalk that makes the route to school hazardous to pedestrians. (Photo by Shawn Allee)

There’s an ideal image of being young
and being in school. There’re the friends,
the apple for the teacher, and walking to
school. Well, the walking-to-school part is
off-limits to millions of children. Even if
they felt like getting exercise, some suburban
kids are too far from school or the route is

There’s an ideal image of being young
and being in school. There’re the friends,
the apple for the teacher, and walking to
school. Well, the walking-to-school part is
off-limits to millions of children. Even if
they felt like getting exercise, some suburban
kids are too far from school or the route is
dangerous. Shawn Allee dropped in
one school that wants to change that:

In the small surburban town of Monee, south of Chicago, police and firefighters are not
used to big protests.

But on the morning I visit, they’ve got one on their hands.

(sound of kids whooping it up)

Cops closed the street between a church and the elementary school.

Five hundred kids, dozens of parents and a smattering of teachers fill up the church
parking lot.

They’re ready to take over the street and march to school.

Parent Arnold Harper’s near the head of the line.

Shawn Allee: “What’s the special occasion?”

Arnold Harper: “The special occasion is about the sidewalks so the kids can get
safely to school. If you’re walking to school, you’re going to run into a part just
before the school. There’s no sidewalk and the kids have to walk out in the street.
Or if they’re riding their bikes, they have to ride out in the street for a brief
moment. You don’t want that – you don’t want your kid ever on the street.”

Allee: “So the school discourages kids from walking?”

Harper: “Absolutely.”

Actually, the parents and the school are tired of discouraging kids from walking.

They want someone: the city, the county, the state – anybody, to build sidewalks between
the subdivisions and the school.

So kids want to hit the street and make noise over the sidewalk issue – only they can’t get
started.

No one brought a whistle.

A snickering fireman takes things into his own hands.

(sounds of honking, etc.)

Kids walk past new homes and corn fields.

I find principal Joanne Jones in the crowd.

Shawn Allee: “In this kind of small town suburban environment, people are used to
driving. What’s the big deal that kids can’t walk to school?”

Principle Jones: “As we know, our country is suffering from childhood obesity and
part of the reason is they don’t get enough exercise. And we feel that if kids get an
hour, sixty minutes, of exercise each day, that would help them be more healthy.”

Allee: “You think if more kids were able to walk, they would?”

Jones: “Yes. We’ve had kids ask us before, why can’t we ride our bikes to school,
why can’t we walk to school? We’ve had parents let them ride their bike, while they
drive alongside. They want to do it.”

If Principal Jones wins this fight, she’ll be bucking a trend.

Very few children walk to school anymore.

Research shows in the sixties, about half walked or biked to school.

Now, only fifteen percent of kids do.

Missing sidewalks aren’t always the problem.

In suburbs and small towns, housing developers sometimes forget about pedestrians when
they build homes.

Heidi Gonzalez helped organize the walk-to-school rally.

She says school district rules and laws don’t always help.

Heidi Gonzalez: “You have to have a certain amount of open acreage when new
elementary schools are built. A lot of developed areas are finding it hard to find nine
acres of space to put a school on.”

Shawn Allee: “So there’s a requirement to plop a school down where they’re on the
edge of development instead of where there are a bunch of houses with finished
sidewalks and other infrastructure.”

Gonzalez: “Exactly.”

So, the school’s aren’t connected to their communities.

The kids had been whooping it up, but their enthusiasm dies when they reach the school’s
flag pole.

As for the adults, like me and Heidi Gonzolez?

We’re left behind.

Gonzalez: “Now we have the dangerous walk to go back to our cars.”

Allee: “Because we won’t have the luxury of police and fire protection.”

And it was a kinda scary to dodge traffic from the school to where the march began.

Watch Where You’re Walkin’

  • Just how easy is it to hoof it in your 'hood? A Seattle software company called FrontSeat created WalkScore.Com. The programmeers claim the site indicates whether a neighborhood offers residents enough amenities to get out of their cars. They hope people will consider the site's "walkability" scores when choosing a place to live. (Photo by Shawn Allee)

Picking a place to live can be a huge
environmental decision. Some people argue
if you can walk to everything you need, you’ll
stay out of your car, and that will cut air
pollution. But how do you compare how ‘walkable’
one place is to another? Shawn Allee looks at a Web site that aims to make that a breeze:

Picking a place to live can be a huge
environmental decision. Some people argue
if you can walk to everything you need, you’ll
stay out of your car, and that will cut air
pollution. But how do you compare how ‘walkable’
one place is to another? Shawn Allee looks at a Web site that aims to make that a breeze:

When urban planners want to know exactly how ‘walkable’ a neighborhood is, they
commission a study, and get results in weeks or months.

One computer programmer says this approach is poky.

“And so we built a piece of software that would let anyone look up to what they
could walk to from their address.”

Matt Lerner helped build a Web site called Walk Score dot com.

You don’t have to be an urban planner to use it.

Anyone can just type in an address, and …

“We tell you all the closest schools, parks, retail stores, so you can see exactly what
that neighborhood looks like.”

Walk Score dot com also spits out a number between zero and a hundred.

If a place scores above ninety, the site calls that a ‘walker’s paradise’.

Lerner says the computer ignores stuff like weather and hills, but there’s a reason behind
that.

“Research on why people walk has shown the number one predictor of whether
people will walk is whether there’s something good to walk to.”

This is all well and good, but does Walk Score dot com work?

I want to test it out – so I ask Lerner to score a Chicago neighborhood close to me.

“If you look at Logan Square, you can see it has a walk score of 86. So if you’re
living near Logan Square, you can get by without driving very often, or even owning
a car perhaps.”

Really?

I head to Logan Square and ask people, does the neighborhood deserve the high score?

Resident: “Yeah, we’ve got a movie theater, a grocery store, restaraunts and bars.”

Resident: “Yes, you can really minimize your use of a car.”

Resident: “Everything’s close – even jewelry stores, furniture stores, grocery stores.
It’s pretty easy to get around walking.”

Most of the people I speak to say the Web site’s pretty much got it right. This is a
very walkable neighborhood. But there’s an activist who works on making the
neighborhood more walkable. He’s not convinced the web site’s got it 100% right.
He says it leaves out some things, for example, this:

(sound of dog barking)

“You’re talking about kids walking to school? That house, that’s a barrier.”

And, Ben Helphand says the Web site doesn’t just miss dogs. It misses other things
that intimidate walkers.

“They should factor in these things that are known to decrease the walkability of the
neighborhood, a big gas station complex, a drive-through bank which is right
behind us.”

Shawn Allee: “Only because they’re hard to walk by, because cars are coming in
and out?”

Ben Helphand: “And because they disincentive people getting out of their cars,
because they’re designed to keep people in their cars.”

The programmers admit the Walk Score site leaves out a lot. Helphand says he’s a
fan of the site, it’s just that it’s tailored to one purpose.

“Their real target audience is people who are moving or relocating and they want
walkability to be a factor in that choice.”

Helphand says the site gives the impression that people interested in walkability have
only one choice to make – where to live.

He wants them to make lots of choices over time.

He wants them to fix bad sidewalks, tame scary dogs, and support zoning laws that favor
walking over driving.

Helphand says if that happens enough, we can make new walkable neighborhoods – not
just rank ones that already exist.

A Spark in Your Step

  • The brace can crank up to 20 watts with each step - that means ten minutes of walking can power a laptop for a half hour. (Photo courtesy of Bionic Power, Inc.)

When you think about alternative energy
sources, you probably don’t include people on your

When you think about alternative energy
sources, you probably don’t include people on your
list. But Ann Murray reports that scientists are
tapping into bionic people power:

Today, we really do have bionic technology.

(Opening of the “Six Million Dollar Man”) “Gentleman, we can rebuild him. We have the technology.”

Okay, maybe not to turn you into
the Six Million Dollar Man. But how about a mobile power plant?

Let’s start with the back story.

About 15 years ago, a couple of young
scientists, Doug Weber and Max Donelan, worked together. Donelan wrote
his grad school dissertation on the energy people create when they walk.
He asked Weber, now a biomedical engineer at the University of
Pittsburgh, to run with his idea.

“He approached me with the idea of building a wearable device that could actually harvest
that energy. And not only generate electricity but potentially make it easier
to walk.”

Weber and Donelan put together a rough prototype in his garage. A lab
tested version of their early demo was just published in the journal Science.
The bionic gizmo looks pretty much like a knee brace with a power pack
attached. Weber calls up a video on YouTube to show me how it works. On
the screen, a guy with a brace on each leg is walking on a treadmill.

“With each step he takes on the treadmill power is generated when the
knee is swinging in extension. It’s during that extension phase that we turn
on the generator and as the traces below the video show, generate large
peaks in power.”

Those peaks in power show up as the hamstring muscle “brakes” to keep
the leg from going too far forward. That’s when the bionic brace kicks in. It
grabs that potentially wasted energy and turns it into electricity.

The brace can crank up to 20 watts with each step. That means ten
minutes of walking can power a laptop for a half hour. No other lightweight
people-powered generator can top that.

Yad Garcha’s betting that people
will be intrigued. He’s the CEO of Bionic Power, a company formed to
market the brace. With some product tweaking, he envisions a world of
alternative energy possibilities. Especially for people who have to depend
on batteries or don’t have much access to electricity. His list includes
millions of people in developing countries, amputees, and soldiers.

“It is a green product primarily for the military because of the number of
batteries that they throw away.”

Garcha says, for example, Canadian soldiers carry up to 20 pounds of
disposable batteries.

“And these throw-away batteries cost a lot of money for them to get them into the
theatre or wherever they’re doing their fighting.”

Garcha’s already been talking to Canadian military reps about field tests.
But the brace probably won’t be ready for another year or two. The
prototype still needs to be quieter, lighter, and more efficient before it makes
its way into the hands – or rather, the legs – of consumers. Better move over
Steve Austin!

Despite the cold weather… there are some dedicated wildlife watchers taking notes,
taking photos and enjoying the outdoors. The Great Lakes Radio Consortium’s Ed Janus
recently joined four people in the snowy woods and fields to watch them as they watched
birds. He brings us this audio postcard:


Noel Cutright: “There’s something happening 365 days a year. Whether it’s in June, in
the height of breeding season here in Wisconsin or in the depths of the winter, you
can
find birds just about anywhere.”


(bird song)


“I think people when they think about going birding in the tropics, they’re always
looking
for the new birds that we don’t have here in Wisconsin. And I was kind of surprised
at
how moved I was when I started seeing some of our birds down there.”


(sound of Bald Eagle)


Mike McDowell: “One way to get people who aren’t really interested in looking at birds
is watching something as lovely as a Bald Eagle. A good place to see them would be
Sauk City, along the Wisconsin River. One time I had a bald eagle there fly right
up into
a tree right next to me. Just a gorgeous view of it in the sun. You can watch them
fly
down from the trees and fly over the water and scoop down and grab a fish and bring it
up to a tree and eat it.”


NC: “Well, we’re starting up a bike trail here in downtown Port Washington. Very
protected. Very close to the lakeshore. I hear a chickadee calling here as we get
started.”


(sound of chickadees)


Delia Unsom: “We used to go out for walks a lot, and one day we were out and saw this
red-tailed hawk circling. And so, you know we were watching that but it was so far
away, so I went out and bought this little, tiny pair of binoculars…”


Chuck Heikkinen: “For twenty bucks.”


DU: “For twenty bucks. And then you start seeing birds up close and then before I
knew
it, Chuck had his own pair of twenty dollar pair of binoculars.”


CH: “Once you get really close to a bird with binoculars, you start to see things
you’d
never imagine.”


DU: “Like birds that we would just totally ignore before – for example sparrows.
Sparrows look so plain, but once you really get into birding, there are certain
sparrows
that are just beautiful.”


(sound of goldfinch)


NC: “Goldfinch flying over. They say ‘potato chip’ when they fly. ‘Potato chip,
potato
chip.'”


“Sometimes if you’re quiet and go out and sit in the woods or along the shore and
birds –
and you’re quiet and don’t make a lot of movement, you can get close to birds. Just
sit
down some place and let the birds come to you. It’s a good way to see them up close…”


(sound of Cooper’s Hawk under)


NC: “There goes a Cooper’s Hawk.”


DU: “Seeing birds is one thing, but hearing birds is another thing.”


CH: “After learning the songs of the birds, it’s almost like being in a symphony.
It’s just
incredibly beautiful sound. Almost like hearing the heart beat of the planet.”


(sound of cardinal under)


NC: “Single note call of a Cardinal. Northern Cardinal – just flew across the path
there.”


CH: “What it does, what it’s done for us I think has pulled the whole state into our
life.
Just all corners of the state we’re pretty well acquainted with because of birds.”


NC: “There’s a White-breasted Nut Hatch I just heard. Yank, yank, yank. Yank, yank,
yank.”


(sound of Nut Hatch under)


DU: “It’s easy to get obsessed with birds, you know? It really is easy. But think
about it:
it’s a great thing to be obsessed about. You know, if you’re going to have an
obsession,
why not something beautiful that gets you outdoors, it brings you out into nature, you
know that makes you happier. There’re just some gorgeous, fantastic days. You know,
in the past we wouldn’t have been outdoors. Now we’re always outdoors.”


MM: “Really all they need is a pair of binoculars and a little bit of time and it’s
great
exercise and why not?”


(bird song fades out)


HOST TAG: “Noel Cutright, Mike McDowell, and the husband and wife team
of Chuck Heikkinen and Delia Unsom watch birds in their home state of Wisconsin. Ed
Janus produced that audio postcard for the Great Lakes Radio Consortium.”
