Pekka, you may also want to visit the U.C. Berkeley Arboretum (or is it
the Botanical Gardens?), which is just across the bay from San Francisco,
in the hills behind UC Berkeley. There is a small but interesting selection
of CP there in a couple of the greenhouses. You might see if Judith Fenn
is available to give you a brief tour of the CP. I've also heard that Peter
D'Amato of California Carnivores has established a small CP collection at
the Lawrence Hall of Science, which is just up the road from the Arboretum.
For sci-fi buffs, the Hall of Science was where the 1960's computer scare
movie, Colossuss: The Forbin Project, was filmed :-).
