Being totally unaccustomed to seeing the need for extreme social restraints, having first come from the bucolic midwest and now living in sheltered Burbank, I initially had not a clue as to what this sign meant. I HOPED it didn't mean what I was thinking; some sort of racial slur. Rather, it meant no gang colors. Duh. Jeanna said in the past they'd had problems but since tightening security and posting signs, it really became quite tame. As tame as these types of things can get, I imagine!
