thanx a lot for ur reply. very impressive.
I think i will go via desert piste if I find another accompany with me. Otherwise i'd better to take the beach piste to Nouakchott,then new road to Atar.
However, how difficult is that desert piste? sure i have never try to drive in desert. but I bought some decent recovery tools. Air jack and sand mats. of course also the shovel. And most important navigation tool, GPS.
so with those assistance, can i go on that route? need some opinions.
