Guns and football games do not match.
Ya you are able to control yourself but think of the guy that comes in, gets ticked at a coach for making a bad call and unloads on him. Guns and spectator sports just don't work all that well together.
And yes I carry a gun, but honestly football games are pretty much safe.
A pistol isn't a weapon, its a tool designed to get you back to the weapon you should have been carrying in the first place.
