I never carried many places, but AAU tournaments seemed like a good time to carry. Several years ago after a rather serious incident of my calling out a team for intentionally cheating that got ugly, they booted the father who was pressuring the scorekeepers from the game.
After the game as I was exiting the gym the guy attempted to physically assault me but was taken down by two fathers of my team who saw it coming. The guys wife then says " I'm going to the car to get my gun". I had mine in the bag I was holding so I quickly went for my car. As I was pulling out of the parking lot two police cruisers were pulling in with urgency. I never heard from the police force but the father who tried to attack me was charged with multiple charges, then in typical fashion all charges were dropped. Made me think twice before reporting another team for cheating, but it happened a couple years later in Florida, but that time the game officials handled everything professionally and simply removed the team from the tournament.
I am surprised with how important athletics is to many dads, this kind of thing seldom happens.
