Probably Rod Knight's Wagon Wheel in Wells. His chips had a large K, for Knight, in the center.
Note the K in the bottom left of the 2nd PC. Why the ashtray didn't say Wagon Wheel or have
an apostrophe I don't know. Maybe an ego thing! I remember playing in there in the 70s and
eating in the restaurant. One time I was driving to Wells listening to Paul Harvey news when
he announced that the "Wagon Wheel in Wells Nevada has been closed for cheating". When
I got there the place was still open except for the 21 game. I never did meet Rod but I knew
his son.
