Do not use demographic characteristics of a VA to make a decision (or the choice of city). Definitely talk to the residents outside of the view of the preceptors. And reputation inflation and power abuse are intrinsic characteristics of the program that can be part of but not necessarily part of the academic culture of the place.
For OR, there's two different VA's, and the one I would recommend isn't in the city that everyone wants to go (not so subtle hint: if you are looking for a good Inpatient VA pharmacy residency experience, I don't suggest looking at any site in VISN 20, but there are excellent nursing home/ambulatory care experiences there if you know where to look and who to talk to). In VISN 12, there's an outstanding residency within that area that isn't well-known in outside VA circles besides the immediate area (and hires well both inside and outside the VA due to its reputation in the area), one residency that is a research powerhouse but has a reputation in the same area for poor resident outcomes as they sacrifice the residents for research productivity, and one that ASHP promotes highly but is not so well-regarded within VA due to preceptor abuse issues and erratic quality control of outcomes.
You wouldn't know any of this without knowing the people. And then there's the VA culture which is very different. I'd recommend you try for a VALOR internship or a clerkship if you still can to get an understanding of the place. It's one hell of a depressing year if you can't cope with the institutional dynamic. There's also a personal fit. One of the residencies in NV is a fairly laid back group of irregulars and the other a regimented serious staff, both have good outcomes, but they don't deal with misfits to their working cultures very well. That's what the interview flushes out supposedly.
