Greg, I'll not be using your coordinates Rumour has it that these are for something called the B3402 I expect that you may indeed find some desert sand there in the near future though. The Tosser is returning soon.
Last time I tried to use yours, Chris-the-fat-twat and I ended up completely the wrong side of Erfoud looking for the Tafilalet Hotel in the dark and a Moroccan on a moped had to lead us there.
I trust that the coordinates for the tossers-on-tour have been personally checked
You could however try Lat: 31:18:31N Lon: 4:05:50W for the Desert Inn.
