Got this off the famous race track(s) website. Its about 10 miles from me, here in the Mojave Desert. It was bought back in 1953 by a friend's dad, Bill Huth. I went thru school with all his kids. Toyota has been the tracks "major sponsor" for about 25 years.

If you live close enough, or are in the area, it would be worth your while to go see an event there.
