Hi !!!
I dont think is a good idea -at all- .
Getting these days a Mauri visa in Casablanca is fast and straightforward. If arrive at the consulate at -say- 11:00h you get your visas by 13:00h for just 10 EUR .

At the border , things can be quite different .For a start , they are NOT SUPPOSED TO ISSUE VISAS , so - at the purest Mauritanian style - they can charge you "deppending on how rich you look". Period. I have seen people paying , from nothing , to 60 EUR at the border .
Secondly , if someone arrives without VISA at the border , they just "look to another place" , and let him in -for a "fee" - but He still doesnt have a visa (Supposed to go to Nouadibou , where - after all - you PAY for a "standard" visa (the one with the nice blue stamps in the passport) .
Without that , you are -then- in the hands of every corrupt policemen (that is , all ) which wants some extra money for you NOT having a valid visa.

-an that can be a nightmare-

Really , getting a mauri visa at CasaBlanca , is probabbly the easiest , fastest , cost-effective operation of all the trip. It takes a few hours (which allow for a fast tourist visit of the city.
Nice place to meet other overlanders also .


Hope this helps.....
