Tri-Valley
From Wikipedia, the free encyclopedia
The Tri-Valley region of California is based around the San Francisco Bay Area cities of Pleasanton, Livermore, Dublin, San Ramon and Danville as well as the unincorporated towns of Alamo and Sunol in the three valleys from which it takes its name: Amador Valley, Livermore Valley and San Ramon Valley. The region can best be described as a bastion of affluent suburbanites.
