TheChipGuide shows this Cardroom in Prunedale, CA but there really is no Prunedale. It is a Census-designated area but really the place was in nearby Salinas, CA. Armin mentions this in The California Guide where he shows the address as 17500 Sierra, Salinas. The place has been closed for 20-30 years now.

Here's the green $20 chip from my $20 chip collection. Yours for $12 if you'd like a 20.
