Ah, the mission at San Juan Bautiste, what a sight. Typical of a newcomer to CA, I've fallen in love with the mission buildings up and down the coast (I've only lived here for 2o years, so I still count as a newcomer.
We may not have more than 200 years of history, but at times, that's all you need. The mission, named for St. John the Baptist was founded in 1797. It is directly on the San Andreas Fault, and was featured in Alfred Hitchcock's Vertigo.
