There's an autocross hosted by TART on March 3rd at Qualcomm stadium. Here's the flyer:
Be sure to register soon if you plan to go, spots fill up fast.
FYI, this is just a practice autocross, their championship is the next day on the 4th, but you only get to do 3 runs if you go to the championship. If you go to the practice, you get 10+ runs in.
I'll be there, my friend with a GLI will be there, and my friend with an A4 will be there. We need to show some Mazda pride and beat those DTM slowpokes.
