I've focused on the southeast on my interview trail, so I'll give you some brief thoughts on each place I've gone..........
Duke--Strong research(but you don't have to do any), great facilities, semi-uptight residents interspersed with some very cool residents, relatively hard working program. If you're thinking fellowship or academics look no further.
UNC--My favorite. About as academically strong as Duke with a more relaxed, friendly atmosphere. Great facilities. Great place to live. Some of the most normal, cordial residents out there. Everyone is smart, but no "stuffed shirts" here.
Vandy--Not quite as strong as the above two, but still a nice place to train. Required research project, not a ton of call, very friendly residents. Facilities not as nice as I thought they'd be, but not bad. New chairman is strong, Nashville is sweet town.
Wake--I don't interview until end of month. Will update.
Virginia--very strong program. Make sure you fit in with the residents here, though. C-ville is very small, and ISOLATED. If your married with kids this would be sweet place for you. Probably as strong as UNC and Duke, just a different crowd of folks.
Any questions????? I'd be glad to elaborate on anything.
