I'm going to second H, though the availability of pork belly roast here (Austin area) is perhaps a few percentage points better, due to the increasing Korean and Vietnamese/Hmong populations.

Generally, an Asian grocery (or Mexican-- there's a chain in TX called Fiesta that caters more to Mexican and South American needs) is the place to go for at least a few of the more truly obscure meat cuts.
