True, but I will say this.
From my past experiences with CR track days, W-body events, and others, from 3-5 is pretty much the dead time and I'd see possibly maybe 10-15ish cars going in the last two hours. Maybe it was busier today, maybe not. Like I said I wasn't there just speaking from past experience. Normally people are packing up by 3:00 and you could hot lap like you were Ricky Bobby in Nascar.
Sucks it was shut down the last couple hours, but shit happens. No different than a Friday night there were the hill-jacks bring out the rusted POS's with flowmasters running 15.0. (yeah, I realize it's a track rental, but again, shit happens) .
I'm out. I get to work tomorrow so I'm going to hammer as many beers as I can right now .
