Thanks GoBruins & Unhedged. That's exactly the type of thing I'm looking for. If anyone else has an opinion, I'd love to hear (see) it.
Coakleym - I have, and had a great time meeting students off-campus. But on-campus seemed different to me. Maybe it was finals, or the weather, or lord knows what. I'm looking forward to the Chicago meet-up so I can get to know some potential classmates!
And all you Round 2ers - don't worry so much. I got in, and I didn't get my invite until almost 7 weeks after I applied. You've got loads of time, and the order you're invited is random.
