On May 19 & 20 is the NMCA Nitto Tire Cup the Auto Club Speedway in Fontana, this even is geared for V-8 Muscle cars.
You can run both days or just one, you get around 12 runs per day and free lunch, it's a very fun event with no work detail.
It's sells out so get your tickets asap, I'll be racing this event also
$10.00 for spectating
