Fairfield, CA is home to one of the oldest native american settlements in the country, with some archaelogists estimating inhabitants over 6000 years ago. Regarded by many as the midpoint between San Francisco and Sacramento, it is also close to wine country and home to Travis Air Force Base. The city is the capital of Solano County.

Spanish settlers first arrived in 1810 with orders to remove the indigenous tribes. Force proved less deadly than the arrival of European diseases for which the natives had no immunity.

On a sweeter note, the city is home to the manufacturers of the Famous Jelly Belly candy, which always found a treasured spot on President Ronald Reagan’s White House Desk. But if candy is not your favorite food, you can always take a tour of the local Anheuser-Busch factory.

Six Flags Discovery Kingdom is nearby, as is the Scandia Fun Center. Fairfield also has numerous lakes for kayaking and fishing, and nature trails and parks for family outings. The citizens of Fairfield feel fortunate to live in not only a temperate climate but a physically beautiful one as well.
