He hit a 4x4" wood pole on the uphill side. With a skidpad instructor in the car. Going backwards & sideways at about 10mph. Knocked it clean out of the ground and destroyed the PVC pipe attached to it that controls the water going to the sprinkler heads. Uglied up his back bumper cover too.
Between that incident and the walls several people including myself almost hit... we decided it isn't worth the risk. Quite simply our goal is for people to have fun and slide around and learn, not to damage their cars and/or get bills for damage to track property (which, btw, he paid the day he received - no problem there.)
But luckily that's not the only skidpad available. If only NASA-MA had a run of events at another road course facility scheduled for June through November...
Stay tuned for details,
