My ex and I spent two weeks out in Cali (about 1980). Like you guys, we loved it. Stayed at the PSA San Franciscan (right across the street from City Hall in San Francisco). It was one of the few large buildings remaining after the 1906 earthquake and was very nicely redone just prior to our visit. Did all the touristy things there but the Muir Woods were the highlight for me there.

San Diego's zoo is TOTALLY awesome and the best one I've ever visited. We knew some people there who took us out for drinks at some waterfront place and we drank our margaritas right in front of John Wayne's boat (a converted PT boat from WWII).

Its a nice place to visit but I wouldn't wanna live there.
