Yes, Chris, I've done one event with them. Very friendly and cohesive group, running a lot of Vipers and Corvettes. John Dearing, who's a very fast Viper racer, runs with them. Low key and not very crowded.
The wrinkle in this December's event is that they're running a race for the fast group, which is going to be totally dominated by some Porsche club racers like Dennis Puddester. It should be fun to watch. And for better or worse (my lap times are more than 10 seconds off Puddester's, for example), I'm in the fast group.
