Heading up the hill towards Grass Valley, just after passing the stop light at Alta Sierra, there is a wide section on the right with a little short-cut of a road leading back in to Alta Sierra. There is often a patrol car with radar tucked in behind a few small trees and bushes. Sometimes additional patrol cars and motorcycles are waiting just past this point at Hidden Valley Rd. Not too far after this point highway 49 goes back down to two lanes, so a lot of people speed up to pass in this area.
