Puzzle Found Here: Ribbons Pictures:   The Burninators' Next Site: Stevens Creek at Stevens Creek The Scooby Doobies'
This site starts at the intersection of Hwy 9 and Hwy 35.
At the base of the stop sign is a small box with the puzzle in it.
The solution to the first part of the puzzle leads to the stop sign at the intersection of Stevens Canyon and Redwood Gulch. Getting there requires driving down a fairly windy, and sometimes pretty steep road. At least one team complained that their brakes caught fire.
The solution to the second part of the puzzle leads to the stop sign at the intersection of Stevens Canyon and Mt. Eden.
