I know about the town but not the program specifically. My brother and sister both lived there for several years -- my brother did his residency there, but not in psych. From what I understand, it's an interesting patient population (very poor, very high minority percentage) with pretty bad access to care.
I wouldn't characterize the town as dirty -- it's actually fairly prosperous, and I think the public schools are good. It's just a smallish town (about 50,000 peolpe and 80 miles away from a big city), so you have to not mind that. The area is very pretty, and you're not that far from the coast.
