Heck there are plenty of parks unused. You never see kids outside playing baseball or football anymore. 30 years ago when my kids were young, every day when I came home from work the baseball field was full of kids playing baseball or football. There were ruts in the grass for baselines. Now they have all grown back and they are never used. The kids are all inside on computers, video games or cell phones.
What they need are more games like that Pokeman game for cell phones. Just drive through Loranger square or downtown about 7 PM, it's full of young people chasing Pokeman. Who needs a park?
