Thanks for the response, that's interesting. Totally true, this trackday was a great deal, $130/day, relative to other NorCal tracks it was a deal.
We did have a rider meeting in the morning and went over flags, and flags are covered repeatedly in the instruction session (which I felt was helpful because I had problems keeping them straight).
The coaches were not introduced at all, but they had orange vests, so they were easily recognized.
I loved the track! Lots of turns, alot of variety, really tight turns where you don't have to be going 60mph to be working on skills (for my level).
Definitely want to go back, but on a budget...
