Amtrak is really nice for medium-distance trips. I've gone from San Francisco to LA, to Seattle, to Denver. You get one overnight, no boarding hassle, can bring on a TON of luggage, and if you're a geography nerd like me you get great views of the landscapes. I work on the train when I do this, so I don't lose vacation days.
