Honestly I would love to go on a safari in either place. What is the one thing that you should make sure to do when in Tanzania though? If you had to pick only one?
Oooh, you like tough questions, huh?

Okay, if I'd only be able to choose one activity in
Tanzania, I'd have to go with heading to Kilimanjaro. My reasoning would be that I *could* grab
a good safari in Nairobi sometime, so having to choose just one, I'd head for the mountain.
