Totally agree!!! I just the the MS 150 from Houston to Austin with 13,500 riders. It was so great to hear people constantly communicating saying "on your left" which just became "left" by the end of the ride. But many people said "Riders on your left" when a group of people were coming by so that you knew not to come over to follow that first person.
I also must say that I had a guy brush shoulders with me and it completely freaked me out becuase he was that close. I saw him later that day get chewed out by the Ride Marshall because of his riding style.
