Just once in West Texas. Wife and infant daughter were sleeping in back seat of car. Out in the middle of no where this joker comes on my tail and stays there for a bit then passes and makes unfriendly jestures. Gets 100 yrds ahead then slows down to 30 and stays there so after a while I pass him and get back up to highway speed. Then his games start all over again so I grab my SP101 make sure its loaded and get into the mind set that if he forces me off the road or stops in the middle of the road like he looked like he was going to he was going down. I wasn't going to screw with an idiot 30 miles from the nearest town and take a chance on my wife or daughter being hurt. He played his stupid little games for 10 or 15 miles then flipped me off and bolted down the highway. To this day I have no idea what his problem was but he was damn close to meeting his maker.
