i actually went to visit the yale med school about two weeks ago. i had also heard many negative things about the surrounding area. but, the downtown area actually struck me as being pretty nice. its pretty big for such a small city, and there are some nice commercial areas there with a lot of stores, restaurants, etc. the downtown commercial area definitely didn't seem unsafe, at least not in the daytime. people there seemed friendly; we asked a guy for directions, and he drove to the spot where we were trying to go. they also have a nice "little italy" district with some very popular italian restaurants. now im sure that some of the surrounding neighborhoods are somewhat seedier, especially at night. but new haven isn't the gunshot-stricken ghetto that everyone makes it out to be.
