The major steam-up event of the year is the Roots of Motive Power Festival on  September 7 and 8 at the Roots facility in Willits.  Plumes of steam and the shrieks of steam whistles will fill the air as a variety of steam-powered equipment is fired up. In addition to the steam-up  across the street at  Recreation Grove Park across will be the Early Day Gas Engine Society and Bill Rose’s Model A Tour group to set up under the oaks. Late Saturday afternoon in the park  will be the annual Roots Appreciation BBQ and raffle  The steam-up is free and open to the public there is a charge for the BBQ.  For more information go to the Roots of Power Facebook Page
