Kilimanjaro and Tanzania January 2028

I am planning on a trip to Tanzania in January of 2028, primarily to climb Kilimanjaro, but also to visit Serengeti NP, the Ngorongoro Crater and Olduvai Gorge, and perhaps Zanzibar, all within a 200 mile radius! Any one that is interested is welcome to join this first meeting. I have a considerable amount of information to share.
