Great pictures, thanks for sharing!
The pictures of Antananarivo remind me of the train ride through the poor(er) areas of Rome, or taking a wrong turn in Detroit.
Where does the trip rank on your list of world travels? I assume it ranks pretty high in terms of culture shock, since Denver isn't really known for its wildlife or abundance of African-American communities.
After a couple of trips to London and one to Rome, I've thought about maybe going to Singapore or Tokyo or Hong Kong/China... or maybe Egypt. Hadn't really thought about South Africa though.
Too many places, not enough PTO.
