Tennessee recently passed a crazy firearms law that allows people with a concealed carry permit to bring their weapons into bars.
I found this out firsthand last recently while out at some bars, when a friend's coworker told us he was packing.
What kind of a person brings a gun with him when he's out having drinks? I don't want to draw too many generalizations from a single observation. But anecdotal evidence suggests that this kind of person is a woman-hating, tea party kind of guy, and generally a thoroughly unpleasant person to be around.
