The easiest route is California 88. Just head to Jackson, CA on SR4 East to the Antioch bridge SR 160 N, then East on Rt 12. It intersects with SR 88 near Lockeford. Be sure to go Left toward Jackson at the light past Clements. Stay on 88 all the way in to Kirkwood. I'd tell you about the Ridge road cutoff but its not that important early in the day. Your mileage is about 155 miles. Count on mainly dry roads. The Highway Patrol makes good money in Amador County.
Yes, will be taking it easy. CHP has made enough money out of me already this year
