Back in my hometown of Atlanta is the main campus of Georgia Tech University, a fine engineering school. And when I say it is "in Atlanta", I mean that it's IN Atlanta; the school's campus butts right up against some of the roughest neighborhoods in town.
I'd always considered it somewhat miraculous that the school's grounds seemed a relatively safe haven in the middle of an area that featured much more prominently in the crime blotter than in the Arts & Living section.
Apparently whatever magic force field there was has started to weaken, and the goblins are getting in amongst the little lambkins with some frequency now. And, despite Georgia having fairly sane CCW laws, the campus is officially gun-free. (Unless you're bringing the gun to commit a crime, that is...)
