Marin County, California as seen from view point of the Golden Gate Bridge

If you are lucky enough to live near the San Francisco Bay, you can often be delighted by the many special sights and sounds there. While in graduate school, both my wife and I lived in Marin County across the Golden Gate Bridge from the city. I commuted for clinical training over both the Richmond Bridge and the Gold Gate. There are a variety of micro-climates and it may be warm one place and a few miles away it may be cool. If you are visiting the Bay Area, check the weather report but always carry a jacket. The coldest time of the year can very likely be summer.
