No biggie. So they know you have a gun and sometimes keep it in the car. +1 on the boy knowing that dad is armed, maybe it will keep him on the straight and narrow with your daughter.
One question though, does MO forbid any alcohol consumption when carrying, or just being intoxicated? If it just forbids being intoxicated, and you were going to have a couple, (assuming that would not make you intoxicated), what is the difference in driving and and carrying your gun?
I don't disarm here in Texas if I am going to have a beer with dinner or whatever. If I am not impaired to drive, then I ain't getting rid of my gun either.
