As noted above, it depends on "community standards." For example: What you might get away with in say, Atlanta, would likely piss off Boss Hogg in Hazzard County.

The difficulty with obscenity prosecutions is that you can't say what those community standards are until a jury weighs in on the matter. Of course, it's entirely likely that a jury in the same town a year later might have a completely different opinion on the same material.
