Not sure if I'm posting this in the right part of the site, as it's not really a ride report, but I came across this film:

You can watch the whole film at:

It's about a couple of american guys riding across the US on those segway upright scooter things. Haven't had a chance to watch it yet, but from the clips I've seen it looks quite good (going to watch it tonight if I get time).

Not exactly a bike tour, but some of the motivations seem to be similar and thought other people might find it interesting as well
