Kentucky stands out because, at least as of last interview cycle, they paid up to $300 in interview expenses. Fortunately for the program, that's the least of the positives..
First, the area. Lexington is a bit rural, but it's very beautiful and appealing even to the NE city folks. The night before, the paid hotel was a very nice suite style place, with everyone meeting downstairs before dinner. The resident to interviewee ratio was at least 1:2, if not 1:1.5, making for plenty of conversation over dinner. The dinner had to have been one of the best I had on the interview trail: no expense was spared, and the residents were very honest with what they thought of the program. To be honest, I don't remember all the negatives, but I remember the positives: decent moonlighting (1-2k a month), GREAT didactics (probably the best of any program), and a comfortable, yet well-rounded schedule. They told me that they work just below or at average hours.
Interview day was nice: Cool folders to each interviewee, as well as a personal touch from the PD, which is not common at other programs. I felt that each interviewer was pretty well-versed with my application, and did a great job selling the program. One of the biggest standouts was the didactics, which, as I said above, ranked second to none on the interview trail. Research wise, I don't remember exact specifics (hey, it was over a year ago), but I believe it was fairly average with a projected upward trend.
The PD is a great guy: Very straightforward, respectful, and energetic regarding his program. Like I said, he knew my file in and out, and even inquired regarding personal aspects of the applicants which were appropriate and thoughtful. The tour was uneventful, but the residents were available throughout the day to answer questions.
Overall feeling: Nice location, nice interview/wine&dine, second-to-none didactics, average but trending up research, above average moonlighting, happy residents, personable and energetic PD, probably not great prep for academics. I ranked them in the top 5, and would have been happy to end up there.
Check came within 1.5 weeks of interview. I'd say it's the top program between KY/IN/OH/WV/Western PA/Most of IL area. Yes, that includes Case and CCF.
