ODduck-
I won't be there on the 2nd but if you are accepted I will see you in the fall. On interview day they give you the option of visiting some of the faculty for an hour. You should definately take advantage of this and go visit who you are going to interview with. It will allow you more time with your interviewer to sell yourself and just shoot the bull. You might be a little nervous at first but the faculty are really laid back. Of course don't just tell them about you, but ask about their lives as well. They are your advocate with the committee and the more they like you the better they will plead your case.
Good Luck.
