Coming from Europe, I have been living in San Francisco for a month, and this is my first visit to America. In two months, I will have to go to Los Angeles for a meeting.

Obviously, taking the plane from SFO to LAX would be the fastest solution. As this question says, taking a bus would be cheaper.

But are there other advantages of taking the bus, for someone discovering the country? For example, is there nice scenery to observe from the bus or such things?
