Tanzania is easily my favorite country in the whole world. Beautiful country, wonderful people, many good friends. When I was there, I wanted to go climb Ol Doinyo Lengai. Really amazing active volcano; looks like the surface of the moon at the top. Convinced a backpacker I met to go with me, but ended up contracting malaria, so we cancelled the trip. Good thing too — we had scheduled the trip for September 4, 2007. Closest I've ever come to dying.
I'd go back in a heartbeat.
Congrats on making it to the top! Hypoxia sneaks up on a lot of people on Kili.
