A valley in Marin County, California, composed of four incorporated 'towns': Woodacre, San Geronimo, Forest Knolls, and Lagunitas. Residents of San Geronimo valley and surrounding areas refer to it as "The Valley." It is a fairly closely-knit community, with a rather liberal citizenry. The farther west one goes in the valley, the more one finds oneself surrounded by forest. The valley is bisected by Sir Francis Drake Boulevard (which more-or-less follows what used to be a railroad), and has numerous hiking/biking trails. Most of the valley's residents reside on the south side of the valley, which is the shadier side. The main businesses in the Valley are the Woodacre Store, Video West, the Little Store, and the Lagunitas store, though there are numerous others.
