Bring a baseball bat. Completely legal, fun to play with, fun to break peoples skulls with.... and i think i speak for everyone when i say i'd be much more terrified of a mutha fucka chasin' me with a baseball bat instead of some dude pulling out a can of pepperspray when i step up to him....

also, you can't get in trouble for having a baseball bat on you, unless a cop sees you destroy property, or use it in a harmful way.
