You'll miss a lot more than your full moons.
I'm not one of those Green faggots but the lack of... you know, plants, animals, open sky, things that aren't made of either concrete, people, or trash and billboards, it makes cities boring. It makes them depressing. Trash isn't fun to look at. Billboards are only occasionally fun to look at, and only for a short time. Most buildings are decidedly unfun to look at. In fact, modern industrial architecture can suck a cock. Make that two cocks. People, they're okay, but they're not enough to make that city an enjoyable place no matter how hard they try. I would send a big 'fuck you' to New York, but then I realized that they're neither Philadelphia nor Gary, and decided to abstain as they could in fact be much worse. It's not just the big cities, though, in fact it's the medium sized cities that are the worst. Just an endless expanse of strip malls and shit nobody cared about five minutes after it was built during a long forgotten 'boom'.
Cities, as they were, were places where you tried to fit as much shit as possible into the tiniest area you could manage, so it's all in one place and you don't have to be there for very long because if you stay for too long, you'll want to hang yourself. You had the city center, where you work and shop and do all that stuff we pricks need to do, and then you left and went home, even if it's just close by. Now we have suburban sprawl with its (vacant) shopping centers and (ugly) housing developments and (useless) parking lots, which is the city planning equivalent of shitting on the floor because your toilet's clogged. You can see this transition in long lived medium-large cities like mine especially, where as you get further and further away from the old growth and into basically anything that was built since 1985, the environment becomes increasingly indistinguishable from vomit.
