Sounds like a good cause. One of the rallyists was a guy of around my age, I guess, on an old BMW 650 or 700. Said he didn’t have any navigation so just followed the cars…must have been a slow and dusty trip for him and he commented how difficult the cars found the piste to Diama (which chimes with my experience last year…it was very rutted and torn up from rainy season that a 2 wheeler was at a distinct advantage….@simondippenhall
Some of my Dutch friends do this every year, to support a school in the Gambia.
They load up a vehicle with school and medical supplies and drive it down. They leave the vehicle and fly home
So far they have bought a plot of land and built a new school building and a medical clinic
