Comments: Rancho Buena Vista is the best-preserved of the old land-grant ranchos. The hacienda is a single-story adobe brick structure in the Monterey style, set on a two-foot thick cobblestone foundation. It looks much as it did over 150 years ago, with no significant architectural alterations having been made to affect its historical integrity, though over the years electricity and other amenities have been added, including bathrooms, interior plastering and hardwood and tile floors. (In the days of the Dons the dirt floors were strewn with Persian carpets.) The furnishings of the Adobe are continually changing with newly donated acquisitions. The La Tiendita Gift Shop on the premises is a fun stop for one-of-a-kind purchases, 941-7639. And don't miss the art gallery. Tours are conducted Wednesdays through Fridays, 10 am - 2:15 pm, and Saturdays, 10:00 am only.
