If this guy want to raise money he need go no further than Saudi Arabia and park his bike in front of the home(s) of any one of the hundred or so Saudi princes. Any one of them, or all, could give him a million $ or so and never miss it. Then he can ride through as many poor areas as he cares to giving the money to the people who need it.
Unhappily, he'll always suceed in raising money from the poor. The poor are always willing to share.
With the untold billions of dollars that has gone into the middle east there is no excuse for anyone to be uneducated, starving, homeless or subject to mindless violence.
All of the problems which are motivating this ride, and I applaud this guy's decision to try to do something, could be cured in a decade by the oil rich states of the Gulf if they simply chose to do so. Good luck to him, but I'll sign up for something closer to home.
