Heal up soon!
I used to do a lot of track days back in the late 90's early 2000's. Like other have said, there always seems to be a portion of the crowd who thinks its a real race going on.
One of my scariest moments was when I was at Pocono (East Course) coming off of the banking, getting ready to come into the infield. You're coming from the fastest section, so you're hard on the brakes, and then you make a left into the infield section. Well, I brake, hang off to the left and start my turn and a bike breezes straight ahead across my brow! Somebody had blown the turn and decided to go straight through the cones at the end of the banked section, but they decided to do so on the inside of me instead of outside of me. Moron! I swear it was mere inches that I missed the guy. I had blown that turn before and went through the cones, but I made sure I went above any other riders.
It used to be that different riding clubs attracted different riders. I used to ride with Reduc and they were the best. When I joined, they had a policy that you had to work an event as a corner worker once before you could ride on the track. That gave everyone a good idea on how trackdays worked. In the early 2000's they cancelled that policy, but the sessions still seemed to be pretty orderly.
Other clubs at the time like Nesba and Team Pro-Motion seemed to be more profit-oriented and had more crashes than Reduc did at the time. Unfortunately, Reduc "merged" with Sportbike TrackTime and my lifetime membership got transferred to them. I say unfortunately, because that apparently decided to give up on the East Coast, and now the club that I'm a member of doesn't offer any track day events anywhere near me. Oh well, I don't really own a suitable track day bike anymore anyways....
I do miss the track, having not done a track day since 2004. It definitely made me a better rider.
