New York City
PKM doesn't like fun.
It's an obvious overstatement to say having fun is completely up to you. But, yeah, you've got to have good people. ...you're more likely to find those people in certain cities, so, round n round we go. Blandiego.
Atlanta is a cool place not listed. Very under-rated.
Seattle is my favorite out of that list, though San Francisco and NYC are really close behind. Denver is a fine city as well. I also like San Diego and Boston out of the major US cities I've been to.
I have a strange crush on St. Louis. Everybody thinks I'm crazy for that one.
What's the scoop on Philly? That is probably the one place no one has mentioned that surprises me. I've never been there though so maybe it's not worth mentioning.
