DAVE AND ARDIS COMSTOCK  began publishing California history in 1979 while living near the former gold-mining towns of You Bet and Red Dog. They had no telephone, and no power except what they produced. In 1989 the Comstocks installed a battery-powered microwave phone link. At the turn of the century they added solar power and a cell phone. In mid-2008, still miles away from any paved roads, they connected to the internet. Ardis died at Santa Rosa in 2015. Dave continues to write, edit, design, illustrate, produce and publish best-selling books about California History.
