Just an FYI, Spring Mountain Motorsports Ranch has added a significant amount of track with 81 feet elevation change and what they call a "high speed spiral".(Probably not to tread on the term "corkscrew") It was great when we were invited there previously, and I have gone independently quite a few times to run with the Las Vegas Porsche Club HPDE events held there several times a year. The new part is the right third including the right straight of the two parallel straights. I suspect that using it in combination with the old section would take out a straight that the Viper guys enjoyed.
