If you can acquire the financial aid for it (or don't even need it), GO OUT OF STATE, it's so worth it.

Oh and for a senior prank, do what I always wanted to do. Take some farm animals and spray paint numbers on their backs, like say chickens, and spray paint the numbers 1, 2, and 4 on their backs and let them free in the school. They will take quite a while trying to find #3! ^_^;
