I was minding my own business. He came up on me fast. All lanes where in use. He pulled up beside me and revd hard. Universal for lets go. So I accepted. It was a bit crowded so we went about 6 times. Pulled on up on him every single time. He was serious, and so was I. We finally stopped going for a little. I pulled up beside him while coasting at about 65. He did a little salute like wave, and then started messing with his radar detector. I could hear his exhaust pipes crackling from heat/cool down. He looked to be in his mid 50's, dressed in a leather jacket, sun glasses, and driving gloves. Kinda funny. Ohio plates. What type of plate is that? Government, or armed services? Not a typical ohio plate.
