St. Louis is a great place to visit and you should try to do the applicant hosting program. I had my interview in the morning before the tour, which turned out to be really nice b/c the rest of the day was stress-free; oh, my interviewer was typing during the whole interview; it was fine--I think she was taking notes, but I had trouble when she asked what I wanted her to tell the admissions committee for me. I kept envisioning her typing everything I was saying word-for-word and so I had trouble focusing, and I wasn't expecting that question.
