Nice! There are also companies that sell bike maps if you want to try your own execution with someone else's planning.

I recently unicycled 300 miles across Africa. Photos here: http://www.matthewwegner.com/africa-unicycle-photos/

This was a vehicle-supported tour organized by Escape Adventures, who are absolutely awesome. They usually do bike tours; this was their first unicycle tour. I'd highly recommend them for any foreign tours: http://escapeadventures.co.nz/
