I agree that we need more kid (and non-bar) adult activities here - especially once the sun goes down.
As teens we could find many ways to entertain ourselves during the day, but once it got dark it was movies, bowling, a party at someone's house, or a bonfire out in a field.
NatureWalk would be a great location for a bowling alley w/ indoor basketball courts, dancing, etc. Plenty of room, already on a major paved road w/ stoplights, and surrounded by the forest so the noise nazis can't have a fit.
And as Susan pointed out, a lot of the kids' behavior is learned from their parents - who sure aren't teaching by example as they stagger and DUI around 30-A leaving their kids unsupervised.
