I highly reccommend going to the school, even for the 1 day Fiesta experience. I went last year as part of the Fiesta Movement and picked up skills that I use almost every day when driving. Animal avoidance, left foot braking, winter driving, autocrossing, car balance, and looking way ahead has made a huge difference in the way I drive on the street and track. Before the school, I always felt a little behind the car when autocrossing, after the 1 day of classes, I felt ahead of the car for a change. I went from a mid pack finisher to 0.1 seconds off from a GS win last year.
