I thought I remembered someone running them for a couple races. Probably back when Etchell's was swapping sponsors every few races.
Largest one on the west coast right here in Rancho Cucamonga
I passed by that one when we picked our puppy up last October. They are building one about 15 minutes from me, supposed to be done by October. I've been to the one in Vegas (WAY too much fun!!).
Actualy they have been aproached by a couple teams..but right now they are trying to sell off some of their cup races on the # 1 car from DEI.... siting increased costs... and slowing retail sales....
