I really liked my interview day at Fresno. Everyone seemed so nice and happy. The children's hospital is gorgeous... I think it's less then 10 years old. They seem really committed to education. They also said that UCSF faculty come out to lecture, and that you have the strength of the UCSF name behind you. Fresno sounds incredibly affordable for a city in California. I like that it's close to Yosemite and skiing, if I ever have any free time.
Some of the drawbacks included that you have to drive to multiple different sites for clinic, NICU, etc., and they might be kind of spread out. Fresno is not much of a city, from what I could tell. I think I might miss the nightlife and excitement of a more urban setting.
I haven't quite decided where to rank it yet...
