Gliding in Africa

Planning on taking a little bike trip around Africa starting next year.
Would like to do some gliding on the way.
Apart from the well known clubs and operations in South Africa and Nambia,
I've found that there are gliding operations in Morroco, Tunsia and
Eygpyt. Don't know if they still have the gliding outfit in Kenya - and I
geuss there are no operations left in Zimbabwe, anybody know?
Anybody know of any other Afican countries where there are gliding
operations?
Any help would be gratefully recieved.
