IIRC Puerto Rican is a bigger boost than some of the other Hispanic divisions. If you do this, I would include something about both the PR aspect and the fact that you are adopted. That's a little bit of diversity too.
In DC, it seems too easy to get into a pattern of going out every night.
i'm between northwestern and cornell and having the same worry re: chicago.
but, on the other side, i've never lived away from a city and i'm afraid that i'll feel cooped up (even though i'm sure there's a lot to do in ithaca). but the isolation and the amount of snow worries me. i'm visiting tomorrow to make sure that nothing about the law library reminds me of the Overlook Hotel.
I had sort of ignored Cornell for a while, but I like it more and more as I look into it. I am looking forward to visiting this week and I really hope they give me some money. The price of GULC is looking pretty high, and I like the idea of going to school outside of a city.
