Hi Tiffany. Consensus is that Tina will be hotter in a train, more physically battered on an old unsprung bus, and will ultimately miss out on a classic route for adventure touring from Wadi Halfa to Dongola. Who am i to argue?
People have advised that most of the route will be manageable 2-up on the XT600E. And that she'll only have to walk a few hundred metres in the sand. My biggest fear is that her period will coincide with a 50 degree day and deep sand, she'll blame me, and i'll hear the Valkyries overhead! I fear her more than the trip itself.
