I always figured in the "Plumber's Butt" regions, and then they just hope it doesn't get entangled in all of the hair when they go to draw it!

I use a fanny-pack a lot, during the summer, riding a bike, hiking, walking, etc. I don't have a dedicated gun pack, they are always black and, as others have said, scream "gun"!! Instead I have a couple of suitable Brand X cheapos that work fine, are of different colors, and don't look so obvious. If someone thinks I'm "light in the loafers", that's his problem, let them think whatever they want, it makes me no less secure nor well-armed.
