In case anyone is interested, a group I regularly open track with is going to Thunderhill the weekend of April 12-13th. There's also a basic driver school available on Saturday morning if anyone needs some basic instruction or is a 1st timer on the track. If you've never run the track before, ride-alongs are also available as well as some informal instructors for ride-alongs after the school. I haven't decided if I'm taking my Mini Cooper S or my Z06 yet, but either way I'm sure it'll be a blast. It's a great track without much stuff to hit if you go off line!
