Tunisia with Adventure Center
A British company that I like is Exodus (Grange Mills, Weir Road, London, SW12 0NE, England; phone +44 [0] 20 8675 . . . From the U.S., book with Adventure Center, 1311 63rd St., Ste. 200, Emeryville, CA 94068; 800/227-8747). They offer basic travel that tries to give you a real flavor of the country.
