Better to drive if you can LA-SF, AAA maps
In response to a forum question:
So many things to do in LA specially if it is your first time. But if you are a good driver and have international license, I suggest renting a car which is so cheap anyway -- there's a lot of good deals that sometimes just charge under $30 a day (sometime even less than 20 USD).
Having a car saves so much time becase unlike in Europe, public transportation is not as extensive in California. But if you can, try to rent a car with GPS, or if you have GPS, bring your own. The drive from LA to San Francisco is nice and can be done in less than half a day, depending how much you stop.
Driving is the way you can understand the California way of life --- traffic sometimes in LA specially during rush hour. Once in SF though, you can just leave you car in your hotel and just use the nice public transportation of trams and buses which are easy to understand. It is harder to drive around the congested "up and down" 45- degree hills in SF...but a nice experience to go through the world's crookedest street! In driving from SF to LA or vice-versa, you can also take the more scenic Carmel route which goes along the California coast (see the map and freeways).
The AAA map is nice and if you have a friend who is a member in USA, they can get the map for you for free and even a little book for free which will outline everything you can do around California.
