Out of tall the huge, famous cities in the world, I'm pretty sure New York was the one I appreciated the least.
Dunno if it was just the streets I was on or anything, but the place reeked of trash. Which was out on the street, in torn-up garbage bags.
Also, WAY too many freaking people for my personal tastes. I prefer it when I can walk down the sidewalk WITHOUT having to shove, or look back over my shoulder and pray to God that the people I'm with know where I am.
However, I really digged Central Park. Place is fucking enormous.
