6 weeks around Lake Victoria

We are three and we are looking for a fourth to join in a bike/drive trip around Lake Victoria, 4 January -
14 February 2011.

We plan to start in Kampala and travel, via the Sesse Islands, south down the west side of the Lake, by rural roads, maybe taking the ferry from Bukoba to Mwanza at the south, Tanzanian, end of the Lake, and another ferry ride from Mwanza to the Ukerewe Islands, then on up the eastern side, taking a side trip into the Serengeti on the Kenyan side, heading north, and finally back around the northern end of the Lake via Jinja to Kampala.
We would like one more to join so we could take it in turns to have two biking and two driving, all costs shared
Is there anybody out there?! Penny
