If traveling N on 49, you come to the highway 12 and 49 split a couple miles out of San Andreas. After taking 49 to the right, you proceed up a long hill going towards Mokelumne Hill. This part of the highway is almost always quiet, not many cars, and is the perfect speed trap. It is a long straight stretch of a hill, but beware of the black and whites sitting right over the top of the first hump. Have seen them there multiple times, at all different times of the day.
