Kingwood residents – what percentage of kids in Kingwood walk or bike to school?

I have a bad habit of letting Google Maps eat up all of my free time, and noticed that Kingwood has what looks like an exceptional network of bike paths. From my little bit of playing around on Google Maps, it looks like you can ride to either the middle or the high school from about 85% of homes in Kingwood without any significant portion of your trip on a car road.

Being the jealous type, I'm wondering – to what extent to kids/families take advantage of this?
