<p>There is a shuttle that goes between Davis and Berkeley (which is only a few miles away from San Francisco). I think there may also be a shuttle from Berkeley to UC San Francisco (the medical school), but I’ve never used it. It doesn’t really matter, though, because the Bay Area has a great public transit system. If you can get to Berkeley (or any other part of the Bay Area), you can just get on a bus or on BART and you can get pretty much anywhere in a matter of minutes. If you have a car, San Francisco is about an hour away (maybe more, depending on traffic…)</p>
<p>You can also get to downtown Sacramento by bus. If you have a car, Sacramento is about 10-15 minutes away. Some people even ride their bikes (although I would definitely avoid that in bad weather).</p>
