I went on this ride saturday, it was pretty cool. Here are some pictures that one of the guys I went with took. Somewhere around 2,000 motorcycles I believe. There weren't too many sport bikes there, I was in a group with the majority of them, one of the guys was riding an R6 race bike, and he found out he had no fan a little over half way thru the ride, that's why most of the sport bikes pulled over.
