Aha! The SCTA (of which I'm a member) is a sanctioning body for LSR and many racers belong to individual clubs, one of which is the San Diego Roadster Club. The "principal" of the Target 550 team is a member of the SDRC. A strange thing (to me) is that you have to be a member of SCTA to race at one of their sanctioned events on the salt flats, but to race at El Mirage (and before 9/11) at Muroc Dry Lake, you have to be a member of SCTA AND one of the recognized clubs. Since Muroc's on Edwards Air Base, it's all closed off now. Ironically, they open up a runway for an event called "The Mojave Mile" that I hope to compete in next year...and that event is run by a totally different organization. It's as confusing as the ACO and Le Mans.
