trip from Paris to Mopti (Mali)
 

I'm leaving Paris at the end of january in 2wd ti Mopti in Mali.

I'm looking for some informations :
- visas : do I need my passport to be valid 6 monyhs after my trip to get visas for Mauritania, Senegal and Mali ?
- is the future road between Nouadhibou and Nouakchott partially made and do I still need a guide to cross the desert in this way ?
- from Mauritania to Mali, the best way with a 2wd is by Ayoun-Nioro or Nema-Nara ?
- if I want to spend a few days in Senegal (St Louis), may I go ther by car with the new law against cars aged 5+ ?
