Event Bulletin Board

  • 3/15/18 - Our customers requested that we run the track CCW, but after reviewing all of the speed and safety issues that are created by running that direction, we have decided to run up the hill as we did last year.  
  • 3/14/18 - PRE-TECH is mandatory PRIOR to taking the track for your first practice session for this event (whether it be Friday or Saturday morning), and you MUST get a sticker from Tech showing you passed PRE-TECH
  • 3/9/18 - Track direction updated to CCW, "down the hill"
