Best safari in Africa

I haven't been on any of the RS Africa trips, but traveled to Kenya/Tanzania, Botswana & Namibia (3 separate trips) in the late '80's, early '90's. While I loved them all, I think Botswana was my favorite - although we were there in a year when a 10-year drought had just broken - there was water everywhere! Including on some of the roads we were supposed to travel... Namibia is also a spectacular country. If you like desert, you should really go.
