Rare in this environment
According to my ordering of the rolls of film, this picture was taken in Ngorongoro. I'm not sure if that's correct, because giraffes are very rare in the crater due to a lack of browsing plants for them.
Oh well, I really like this picture and the next one, so for now, we'll place them in the crater, even if they may have really been in Tarangire or the Serengeti.
UPDATE: My friends at Thomson tell me that this picture was taken in the Mulanga Depression between Ngorongoro Conservation Area and the Serengeti plains (as you meander downhill to the southern plains from the Highlands).
