If you want to do a real good Bush flying course then join Bush Air in South Africa. Here is the website:
Bush Air - South Africa. Extreme and highly advanced Bush and Mountain Flying and Training.
The owner is a super knowledgable chap and a safe pilot. Tell you what, you will learn how to properly fly your a/c.
When you done, then come join the Kalahari Flying Club in Maun, Northern Botswana. Here you can do hire and fly on a Cessna 172.
Hope this helps!
