1. Watch your money - the dollar is the most sought after commodity there and you will be relieved of vast amounts very skillfully if not careful.
2. Rog. Mana on the aids - stay AWAY from the temptations you WILL be offered (in exchange for the dollars)
3. Dont fly Air Tanzania. I was nearly first in line at the Kempton Park Wimpy one day, the take off from 03L at JIA was more of a thrust / drag / lift miracle than flight...!
4. There is a big mountain there - try to avoid hitting it...!
