Orange County Auto Body Shop? Skateboarder's Club?? Sandwich Shop???
I don't know for sure, but this is what I dug up from AP.com:
"Next week on Tuesday is the premiere of "King of Vegas," which I made a couple posts about before the auditions in October. I know several people who tried out, and you'll be able to watch two of the West Coast Grinders compete for the title."
That was recently posted by Bettie. Maybe we should ask her.

P.S. - Maybe they all work in a machine shop????
