Yes, all the rancheros are gone. California’s history has been mostly paved over but put away your handerkchieves. Our early Mexican days will be-created this Saturday, March 16 from 12-3 at the Los Altos History Museum. Demonstrations of brick making, sheep shearing, wool carding, roping, blacksmithing and saddle making will bring the Museum’s current bi-lingual exhibit, “Juana: Dona de la Frontera”, (which runs until March 31) to life. Free.
