&gt;There&#x27;s no real public transportation to&#x2F;fro Marin to San Francisco<p>After the loans on the construction of the Golden Gate Bridge were paid off (some time in the 1960s or 1970s) instead of eliminating the tolls, it was decided to use the revenue from the tolls to subsidize public transportation between SF and the counties to the north of it. The buses and ferries between Marin and SF remain very good IMHO.
