Last night me and my GF went out for a late dinner. She drove because I would have a few drinks and plus in my old age I don’t see very well at night. We get in a middle turn lane to make a a u-turn and three is car I front of us not moving. There was no oncoming traffic and we couldn’t figure out why he was just sitting there. GF honked her horn and the guy pinch his gas made a u turn and then stopped and started to open his door. We fly past him and he follows us for a couple of miles flashing his lights at us every now and then. Finally the guy passed us and turned off in another direction. I don’t know if the guy had a gun but we thought we were about to get shot at. Very possible it was just a young punk trying to be tough but the threat was definitely there. If that occurred we had no defense. I need to change that. GF has a dash camera and we are thinking of taking the video to the cops just to say hey nothing happened this time but this guy could do something in the future.
