• Take a train tour the entire length of the Trans-Siberian Railroad.

Let me edit this slightly, as the railroad tends to fork off somewhat. I want to start back in London, giving Paris another shot, saying hi to my favorite city (Amsterdam), and stopping by Berlin on the way to St. Petersburg to see the ballerinas, through to all the little (and big!) towns of Russian (hi, Moscow!), down through Mongolia, Belarus, China, and leave out of Saigon.

Who’s game for a month long excursion (possibly longer)?
Now if I can just manage to come up with about $3500.
