While on the Grand Performance Sprint ride, at the intersection of Cliff and Johnny Cake Rd. Joe Christian, who leads Mello Velo tours was hit from behind by a pickups passengers mirror on the left shoulder. Lucky for him, and he told me so, that the big mirror was ducked taped on so it broke away very easy. Dan Casebeer said that the pickup came very close to him while riding behind Joe. I was right behind Joe and to the right so I could see the whole thing. The driver sped away knowing what had happened. If Joe would have been just 1 ft. or less further to the left we would have been making a 911 call. The driver of the pickup had alot of room to avoid all this but he was the 1/10th of 1 % of the drivers who have this mentality towards bike riders on THEIR road.
