I've been there for two days, just got home. It was awesome, and aside from the races, there were more motorcycles than I've ever seen outside of Daytona Bike week-thousands. Spent yesterday in the infield viewing from various spots and checking out all the stuff, and today we watched the races from great seat above turn four-we could see turns one through five.
Saw one XS650 tracker yesterday parked near us in the infield.
