In the next couple of years I hope to get a cowboy style revolver.
That year at Halloween I'm going to dress up as a cowboy and open carry. Open carry is legal where I live anyway, BTW, so I wouldn't be breaking any laws by doing it at anytime.
But no one will notice on Halloween.
Just be careful you don't shoot the neighbor's Jack O Lantern thinking it's a real monster
throw on the fatigues and just bring M4s and sigs. if it makes you nervous get your flash hider and bolt anodized orange.
