Eastbound Hwy 37, just past Novato Creek (approximately one-half mile east of US 101, CHP will park on the right shoulder half hidden by a large bush and will catch cars coming off the peak of the Novato Creek bridge traveling in excess of the posted speed limit of 65 mph. Can be any time of the day or night, not usually during rush hour. May also park a little farther down at the short dirt road leading to the field south of Hwy 37.
