My pictures sucked because I had a crappy camera:
AutoX oddity #1:  A pair of Morgan roadsters
AutoX oddity #2:  Those same Morgans hauling ass
Even this big boy got into the act

Cop brakes, cop engine, cop suspension...
More competitors
And a Z06 that was insanely fast
The reason you don't bring all-season tires to an autocross event
A frustrated auxocrosser who eventually resorted to drifting
I'll be back in a month with better tires and better times.  Fastest time was 46 seconds, my fastest was 53.
