As much as I enjoy a group ride it can turn ugly quickly especially when you have so many different bikes, attitudes, and skill levels. I go on a group ride every summer with about 30 bikes. We left early one morning on our way to the highway and not only a half mile from the starting point 2 of the riders went down when a car backing out of a driveway took out the first guy on his brand new bike. The second guy behind him locked up his brakes and flew off the bike. We all stopped and blocked traffic with our bikes in the road until the police, ambulance, and tow truck came and we gave that guy in the car such hell he was shakin like a leaf. We all stuck together helped out and continued our ride without any further problems.
