Good luck to you on your trip to Kenya. I am jealous of this opportunity to spend that kind of time in Africa. I have two dear friends from Africa. One lives in Nigeria (Outside Lagos) and the other is from Burundi. I have always wanted to visit Africa but the expense is pretty daunting.
Are you taking any big glass and do you expect to be able to get out for wildlife shots? Whatever you do it will be a wonderful experience I am sure.
