I just got back from DANL, and it was fantastic. I was blown away by the school and (probably more importantly) the people there. I have no idea if I met any of you or not, but nearly everyone I met and spoke to this weekend was someone I'd be happy to have next to me in classes for three years. Kudos to the admissions committee, I guess 
I completely agree with you, I now appreciate the interviews. All the new admits and current students were very friendly and laid back. The professors and staff were really interested in the students. I went to the mock civ pro. class and although the prof put someone on the spot it wasn't painful to watch. I put down my deposit after lunch, that was how fast I was sold. I can see myself having fun at Northwestern.
