If the Thermal Motorsports Track is indeed located adjacent to the Jacqueline Cochran Airport it has some of the same issues as Chuckwalla.
HSR West ran the Palm Springs Revival there in November 2005. Many very valuable and collectiable vintage race cars went home needing new windshields and paint jobs as a result of the desert sand. I was a little more aggresive while over taking Mark Wichman's 911 I dropped a wheel off the track and rolled several times in their damn sand!

HSR never went back. HSR did run Chuckwalla a month ago and will probably never return.
