wished you had brought to Maun with you once you arrived?
More money?

A better tent.
Mine "died" after 4 months, it just couldn't keep the rain out any more. A couple other tents I saw also reached their limits. On one, a pole snapped under the weight of a storm. On a few the zippers didn't hold up.
I should have spent more on the tent, it would have saved on headaches as well as the cost of having to hire a room for a couple nights.
Diarrhoea meds.
It's a brave person who farts in a bar in Africa.
