I've been into motorbike travel books for a while, and one of my faves is 'One man caravan' by Robert E. Fulton Jr.
When I heard there was a 1/2 hr film of it, I had to get it.
'Twice Upon A Caravan' has Bob at age 90 showing some of the footage he took in 20 countries. And amazing shots of him riding through sand & mud using his legs as stabilisers!
If you're into this genre, check it out. It's on DVD from Whitehorse Press in the USA.
