That probably is the SCCA Street School. That group emphasizes safety and if they do it like they have done last year, they will split the track into 2 sections (east and west) and have the advanced on one side. I highly recommend it for people who have never driven Thunderhill. They will also use cones to slow people down for Turn 1 and if they open up the whole track, do the same thing to slow you down for turn 7 & 8. This is a great opportunity to get familiar with Thunderhill and then sign up for Skip Thomas's Viper Days.
