Wow... similar story here... was an SCCA member years ago, then discovered open-track events - forgot about autocrossing and run with SCCA, NASA, Touring Car Club, Green Flag, basically as much track time as I can get... but that's not in my L - that's my A-SP Mazda RX7. Since I got my L I've done a few road-course events with it... and I want to autocross it too... so I re-joined SCCA a few weeks ago.
If you're in NASA... we've surely seen each other... were you at the Laguna Seca 3/3 event? That was fun until it started raining

(not w/the L - IMO, NASA is too hardcore for the L.)
And I'll check out the Shelby Club website... April 7 - Thunderhill might work! Can any car enter? Will I get dirty looks if I show up in an import or my Lightning?
I'm going to Buttonwillow April 13... Wanna go? (might be a spot still available):

Anyway:
Both Jeffs need to sign-up for SCCA and start autocrossing! I cannot make the March 11 date, but I'll be at the March 25 event.
