Mill Valley is a city in Marin County, about 14 miles north of San Francisco, on the western and northern shores of Richardson Bay and the eastern slopes of Mount Tamalpais. The first sawmill in the county was built on Cascade Creek, now Old Mill Park, in the mid-1830s, and the city was incorporated on September 1, 1900. The rig crosses the valley from the foothills for repairs and fabrication at homes, shops, driveways and jobsites across Mill Valley.

Beyond the flat coastal area and marshlands, Mill Valley fills narrow wooded canyons, mostly of second-growth redwoods, and two streams flow from the slopes of Mount Tamalpais through town to the bay. The Mt. Tamalpais and Muir Woods Scenic Railway once ran from here, and the Panoramic Highway to Stinson Beach was built in 1929 and 1930. Utility trailers, truck racks and yard carts get repaired right where they sit, because the rig carries engine-drive welding power, wire feeders, an oxy-acetylene torch and a plasma cutter.
For directions, a landmark helps: Old Mill Park, Lytton Square and its former train depot, or Miller Avenue.
