River Rock has an extensive free bus system from all parts of the Bay Area.

River Rock (Geyserville), $1-$2-$5 JW2, NSUD, Jacks, $1 99.98 OEJ .2 cb (also might be .25-50 FP games on the OEJ bank, didn't check them).

Mostly TERRIBLY VP machines, but I WAS able to find a bank of 6 Uprights in the very back room (NE corner) of casino that had ONLY 9/6 25c JoB on them.

I visited River Rock today, checked 1 of about every 5 machines. JoB paytables by denom: 5-10 cent - 6/5 (ouch); 20-50 cent - 9/5 (saw a few 8/5); $ - 9/6 (ding!) scattered throughout the small casino, and I only play JoB so I can't say anything about other games.

River Rock has several $1 MG/MD NSUD and 9/6 Job near the restaurant area. Cash back is 0.1%.

A new casino opened recently in Sonoma County, California. It is called River Rock and is located near the town of Geyserville. At River Rock I found a quantity of full pay 9/6 Jacks or Better for $1, with lower payoffs at quarter and 50-cent levels.
