Teenagers these days listen to the worst music ever invented and say they listen to "punk". There is definately a group mentality. If I lived in the city I wouldn't have minded going car free as a teenager (I'm only 21 now). Hell, I biked to school all through middle school so I may not be the best example. It's hard to explain to someone that age anything that isn't their own perspective because at that age it is extremely hard to see any other perspective than one's own. I think that is where all the problems of being a teenager come from, not being able to see other points of view. Just talk to your kids and see what they think.
