Pleasanton is known today as the "City of Planned Progress," home to tech companies, grand houses and the Alameda County Fairgrounds. A century and a half ago, however, it was little more than an idea--a real estate project in the Bay Area backwater conceived to profit from the railroad's advance through the Amador-Livermore Valley. Discover Pleasanton's evolution from open range to a thriving modern city. From the Ohlone encounter with the Spanish to the city's formal incorporation and beyond, author Ken MacLennan and the Museum on Main offer up an incisive and detailed look at Pleasanton's history.
