This is an important point. In my hometown, I spent a lot of time playing in vacant/double/unused lots. Those lots are all gone and have been turned into parking lots or mini-McMansions. It breaks my heart every time I visit my parents' house and I see that our old soccer, football, wiffleball field and all of the trees we used to build forts have been replaced by cheap houses whose lawns are covered in a rotating cast of inflatables.

I can't fault the landowners for cashing in on their spare property but it would seem that the town could do with more localized parks. If anyone has been to Alphabet City in NYC, a lot of vacant lots were turned into community gardens and they're incredible little oases to stumble upon and relax in for a few minutes. I wish the town had had the foresight to do this with some of the aforementioned lots.

This is a major aside but another major change is that >50% of the trees which used to dot my hometown are gone. They either fell, died or got in the way of the power lines and were not replaced by the town or property owners. The streets all used to be covered in leafy canopies, everybody's houses were a few degrees cooler and all of that wood prevented a lot of the noise pollution from the Metro-North and I-95 from making its way through.
