It's in the rules, but have you ever seen them use it?? I haven't.
I saw the blue flag used in Allen's Corner, on Sunday, during (I believe) the CSBK Superbike race. Surprised the hell out of me.
Guess you weren't there last year if you thought that this year was a small crowd.
The fly over at departure over the bikes on the track was cool.
Last year the crowd was bigger.
