Iiiiinteresting. Where are you staying at? To make things interesting, how about couch surfing? I've met some international travelers through Hospitality Club before and my friend regularly hosts people to stay at her place for free in SF. If you travel light and don't need to leave expensive stuff around, it's a good way to go.

Greyhound is okay for some travel within 3 hours. Anything longer and you may as well start torturing yourself now. I haven't been on Amtrak yet, but I've heard positive things about their more popular lines, like up and down the West Coast. Beware of the connecting trains that take you part way and dump you on an Amtrak bus the rest of the way.

I'm sure some members here would hang out and show you around, keep us posted on dates.
