About four years ago I was leading an SCRC group on a ride on a county road. This road is very twisty in some spots and we were starting up a steep hill when a dump truck comes flying down the hill and around a turn. He was in the middle of the road as well. I was certain that he was going to wipe some of us off the road, luckily he missed all of us. We did stop to regain our pucker factor then I stayed about 100 yards ahead of the gang with my flashers on to complete the ride.
