I concur with Cesco's comments.
AAP is great. Having a 2L or 3L to ask questions, get study tips, or just rant is a major major plus.
Other positives -
The building is accessible 24/7. All you have to do is ask student affairs and you can get into the building at 3 o'clock in the morning if you want to.
There are so many student organizations. Not only do they have free lunches, but they bring awesome speakers. Think Justice Scalia last year, Judge Edwards (former member of European Court of Justice) and Former President of Poland (can't think of his name) just to name a few. It seems like there's always something going on in the building. Oh, and we a lot of great journals you can get involved with. I'm sure that's the case for most schools. Our Law Review is 100% write on - which allows everyone a fair chance to get on the board.
Right now the only thing annoying me is the weather. Oh, and the reading I have yet to do for con law.
When you come to visit, be sure to go to the forum and sit with some current students. Let them know why you're there and ask questions. Unless they are studying for midterms (in which case they shouldn't be in the forum anyway) or frantically reading for their next class, they should be able to help.
