I had a guy threaten to shoot me in Kentucky once when I was working with him on the Ohio River - more of a 'I have a rifle in my truck' than a 'pointing a gun at you' kind of a threat though.

If you commute long enough through places of high poverty you'll have some stories. I'd get a gun pulled on me for driving. I'd also have friends and colleagues brag to me about pulling guns on other drivers. I'd tell them they were crazy but in their mind it's a completely valid reaction.

It's used as a joke in a lot of circles. "My daughter's old enough to date, I better clean my gun"
