Trevor,
My wife is from the Kilimanjaro area, sort of near Machame
If you have been there you've more than likely heard of the Chugga tribe, she is one of them. I found out too late about them!
She is currently a Lecturer at the University of Dodoma though, much different area than Moshi. We're building a place near Kili for vacations though, ( may someday live there) Its pretty much done except for laying the tile floors and finish plumbing / electrical.
Good photos that you posted, we got several like those last year when we did Ngorongoro Crater, Manyara N.P.and part of the Serengeti. Awesome to see huge herds of zebras,lions, etc. Even found one black Rhino in the crater.
