I appled to very few program in the South/Southwest, but will gladly give you info on what I do know.
Univ of FL - AWESOME program, cool town (esp if your a single person). The Chair & Chair Emeritus are superb! The weakest part of the program, in my opinion, was the structure of the CBY. Prior to my app year, it had been a Dept of Anesth run internship that was heavy in options & critical care. However, due to some financial issues, that was dropped such that 1/2 of their interns did a surg internship & the other half did an IM one. Other than that, I have nothing but accolades for the program.
Vandy - ended up turning down their invitation. I met a couple of Vandy MS-4s on the interview trial. Neither one of them had applied to their own gas program. Both said the program had had problems in years past but was on the mend...but not to the point where they would have chosen to go there. I met these 2 on separate interviews.
Wash U - rejected me outright...nice, polite rejection letter - very similar to the rejection from them when I applied to their medical school. Oh well, no loss of sleep there. St. Louis is a pretty cool place though...very mid-western, sort of a mix of Southern & Northern cultures...be aware though, the food in the mid-west is way bland. Those folks are afraid of spices - they actually think salt & pepper are SPICEY!
Univ of Ark - largely, I applied there to keep the family happy...I grew up in Little Rock, but have not lived in 10 or so years. As I understand it (that means the following is hearsay from multiple sources), the UAMS program had several years of severe problems. They could not keep a stable Chair or Program Dir - and for anyone who ever played sports, you can't have a winning team w/o a solid infrastructure! Allegedly, an immediately past Chair even went to the pokey for embezzlement or something...again, this was something I heard from chatter while I was interviewing there. I have no idea as to the factual basis. Anyhow, they now have a real Chair...had been the interim Chair for a couple of years...& 2 guys are sharing the PD slot. If I correctly recall, one of them was from UFL & the other from Univ of Rochester. However, I found myself very underwhelmed by the newly appointed Chair. I think that this is a diamond in the rough...just a bit too rough to earnestly consider just yet.
