There is a rallyx this sat up at johnsonvalley. Same as an autox but in the dirt. I did one awhile back at the Del Mar fairgrounds and it was a blast! Three of us shared the cheapest FWD rental-30 split. It was a chevy aveo. It is a great place to practice car control -oversteer- understeer as everything is exaggerated.
