Hi Ken,
Some very nice work here !! I noticed your absence at BPN. I infrequently visit as well. Miss your photographic work and wildlife ethics.
I am in the early stages of trying to visit Mana Pools. Self drive is a difficult trick to pull off from Alaska - with camping gear etc... and logistics in Zim. Will likely go with an operator. Any advice as timing? Looking at April/May or October/November 2014?
