It's not at all helpful that the current trend in school construction is to build on the outside perimeter of a developed area often only accessible by a highway or other high traffic road.
Once schools were developed within the neighborhood. I'm fortunate to have a middle school that will be accessible by bike for my kids. Also, I'm involved in trying to get our city to develop access to our local high school for bikers and walkers. We all should get involved in making our officials know our concerns regarding this. If you're not, you're just wasting space on this thread.
