The subtlety of the head banging eludes me but I have removed my post which suggested that people run a full research search on previous posted information before posting their own questions. In the great spirit of African fair play so beloved of the colonial masters let me say that indeed it is a good idea to go to Maun and deal directly with the charter companies. Whether one can bribe one's way into a job by offering large amounts of $s or one's sister or a camel is a topic as yet fully unexplored. The success of such a venture would depend upon various circumstances not the least of which would be, perhaps, which way the wind was blowing in Uganda.
