They're not necessarily "crappy" in that they don't care about teaching, they're "crappy" in the sense that they're smaller community hospitals where you won't see anywhere near the same diversity of pathology as you would at a tertiary referral center like the UPMC facilities. You'll see mainly lots of bread and butter things, helpful in a clinical setting of your future practice (as those are the same bread and butter things you'd be seeing), not so helpful in a boards/shelf setting. Community hospitals have their perks though, you're not fighting fellows and residents and interns and other students for procedures, you usually get more autonomy, stuff like that. Both community hospitals and tertiary referral centers have their ups and downs. As my last attending put it best, you can be a big fish in a small pond or a small fish in a big pond, all depends on what you want.
