Well, back a number of years ago, before Virginia's change to Shall Issue, I had such an incident.
Was transporting my UNNLOADED .38 Special, riding my bicycle, after dark along a Fan District seat, when a car with several idiots in it yelled at me while driving by. I insulted them right back, which admittedly wasn't the brightest thing to have done (but I was young and dumb).
The car swerved in to block my progress, and the guy in front-right jumped out. He said something about kicking my hippie a__. Then I pushed the hem of my jacket back and put my hand just above the butt of the gun . . . they left, real quick.
