Actually, the location issue IS key. It is REALLY far out there (about 2 hours by train and 1 to drive IF there is no travel) the vast majority of people who apply to residency in NYC want to be IN the city (or at least brooklyn, queens, bronx).
Stony Brook is a really good program. I interviewed there. I liked the program alot but again, its WAY WAY WAY out there and for that reason and that alone, I ranked it very low.
as you see, LOCATION is becoming a key factor in many people's decision to rank a program.
