Libyan visa at Ras Adir
 

The Dutch LandCruiser club claims in their "Sahara field guide" that it is now possible to get your visa at the Libyan border with Tunesia (Ras Adir). They organise group trips to Libya so should know. Also the info is very recent (March 2005).
Can anyone confirm this? Do you know if you still need an invitation letter and/or Libyan guide to meet you at het border?

Thanks!
