You want to travel by train from Moscow to Vladivostok, but you're not sure whether you are ready for the 10+ days without a shower and the smell of salted fish from your neighbor's zakouskis? Here is a cool link for you: http://www.google.ru/intl/ru/landing/transsib/en.html
Click anywhere on the blue line on the map representing the railroad, and you can see a movie from 7 to 30 minutes of what you would actually see from the left window of the Transiberian, with nobody to tell you not to lean outside. Strangely enough, on the left window, it is always daylight, always sunny, and always summer.
So, chose the soundtrack (the page proposes rumble from wheels, Russian radio, or the full audio version of War and Peace...), sit back and relax.
