Yep, Kansas just passed the concealed carry last year (?) and we've got a lot of the gun signs going up; I suppose this will keep the places from being robbed at gunpoint!
JWBoyd - My cousin's husband is a truck driver and he's carried a gun for years in a well-hidden place in his truck (no I don't know where). I would imagine that a lot of truck drivers fancy themselves to by gunslingers or in danger.
