Not sure about Slim's sleeping on autopilot tale. The story I heard was, someone (Slim?) was flying toward Las Vegas and saw a green circle of shrubbery below. Making note of the area, he returned (on Route 95) and determined that there was water underground. He bought the land hoping for a decent well, which he
got, and the casino and little town were born.

I wsad told that Cal-Nev-Ari hosts live card games only one night a year to maintain its lilcense. Slots-only on the afternoon that I visited. Don't know when that magical night comes round. Yes, I think some new owners bought the town recently.
