Did group ride last weekend as a fundraiser for UW and was asked to explain some basic guidelines as I was one of the most experienced. Explained the basics such as not running stops, no side by side, riding to ability, etc. I took the back of the group and was horrified with two rookies who insisted on going side by side. Talked to them at scheduled stop and they litteraly told me to FOff. They were given an alternative, follow the rules or drop out of the ride. They elected to drop out,. Too bad, but was in the best interest of the group. Nerver ride side by side.
