I have lived on S 40 for the last 4 years, and in the Sausalito hills for 20 years before that. When I was a graduate student at UC Berkeley in the 1960's I lived on a Higgens boat that I bought in Sausalito and had towed to the San Pablo marina. I sold the houseboat in a year to someone in Sausalito, so it may be in Waldo Point now! I am a retired biochemist turned marine biologist. My book "Life on the Dock" is for sale on Amazo. I now do research on animals called Tunicates, which do live on the sides of the dock.
