Discription of Events: At Lowe's intersection, turning left to northbound on highway 93. I was behind him, and followed in turning left. It was raining, so I knew I would be driving slower and turned left and moved into the slow lane pretty quickly. In there intersection, there was a woman turning right into our lanes--she was way into the intersection, and I thought she might hit me, so I accelerated. I passed the Ford truck at issue. His intention was to turn right, and so I was at this point probably in his blind spot, or at least in his way. At this point, rage occurred. I heard someone LAYING on the horn, but had no idea who. The Reserve Rd intersection was way backed up in the outside lane, so I moved back to the inside lane. 4RPHUN anger-issue man was, by now, in the right turn lane. He stopped to get even with me (two lanes over, thank goodness), rolled down his window, leaned his bald-headed, lean body fully outside the window and started yelling at me and flipped me off. He looked absolutely ridiculous, so I pointed and started laughing when I realized he was screaming at me. Really, his overwrought, hysterical reaction was completely out of proportion to what was clearly a non-malicious event. I believe he was just projecting anger about something else--had to be. I blew him a big kiss, turned away, and kept driving. Just a warning though--his trigger is tight and I'm glad I wasn't in arms length of him. Beware--scary, petty little man.
