You came all the way to Monterey from Denver?
You have people with money in this area and north of LA that like tracking their toys. Last fall I participated to a low key track day meeting at Laguna Seca and there was the new GT2, 2 GT3 RSs, 1 modified Turbo, 2 GT-Rs, 1 spanking new modified Viper GTS (flashy green, pew...), couple of Elises, F430 Challenge Stradale, Corvettes Z06s, Stingray competition (must have been a kit car though), pumped up Mustangs (all GT tastefully modified), 1 ACR, ... and a race prep GT40 from the 60s.
