One of our last original neighborhoods goes on public display this Sept 14 from 11-4. It is the Floating Homes Tour on the north end of Sausalito at Waldo Point. The architecture is fresh, often eccentric, and the views of the Bay are close to priceless. Owners of 15 homes here will serve as your generous hosts and tour guides. It starts at the small Kappas Green park which promises a picnic. Lively music. $50.
