If you've got a car, head up Alum Rock Road to the Observatory, or cut over to the coast and the seascapes South of Half Moon Bay. For architecture theres the old Mission San Jose, Stanford University in Palo Alto, and the dirigible hangers at Moffat Field (you might need permission for Moffat in the post 9-11 world--call first if your planning a visit) For the truly wierd theres the necropolis of Colma, the Rosicrutian museum(is that how you spellit?) and...those dirigible hangers at Moffat Field, and for seafood check out The Clam Bucket---yum!
