Rohnert Park is a city in Sonoma County, about 50 miles north of San Francisco, named after the Rohnert family, which owned the Rohnert Seed Farm. It is an early planned city, incorporated in a summer election in 1962, the first town to incorporate in Sonoma County since 1905. The rig crosses the valley from the foothills for repairs and fabrication at garages, shops, homes and jobsites across Rohnert Park.
Highway 121 through the Carneros region to Highway 116, which crosses the Sonoma Mountains on Stage Gulch Road and comes into Petaluma as Lakeville Highway. Highway 116 then runs with US 101 north to Cotati, and US 101 continues on through Rohnert Park.

The neighborhoods east of Highway 101 are organized into lettered sections, and in most cases the names of streets and parks begin with the letter of their section. Roberts Lake, a small reservoir, sits at the north end of the city, and Copeland Creek, Hinebaugh Creek and Crane Creek all run through it. Utility trailers, shop benches and engine stands 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: Roberts Lake, the SMART station, the Laguna de Santa Rosa, or your exit off US 101.
Yes. Waldo Emerson Rohnert bought a large ranch here in 1929 and built a crude drainage system against the flooding, and his son Fred grew it into the Rohnert Seed Farm, a major horticultural success for the county. US 101 brings the rig up from Petaluma. Call or text and we'll set a time.
Yes. A sprung trailer ramp hinge, a cracked engine stand, a broken shop press frame and a bent hitch receiver get welded right in the driveway or the shop. Text a photo and the street and we'll plan the trip.
Yes. The Laguna de Santa Rosa forms part of the border with Cotati, which voted to incorporate the year after Rohnert Park did.
