The first class safari camps tend to lose the 'Africa' feel to them. I too love the fly camp, as long as you get your basics.
I had the experience of 'roughing' it when we were after leopard, and needed to be in the blind by 4am. It was a brilliant experience,sleeping rough, digging holes in the dry river bed for cool clear water, and eating sudsa and African stew every night. However, at the end of a few days in the bush,I do recall the absolute luxury of being able to get into a tent, having a shave, hot bath,clean sheets and a creaky bed .
Even being able to get a bit of milk in one's mug of tea was greatly appreciated.
The camp run by John Knowles sounds very interesting, as Zambia will almost certainly be my next hunting destination.
Any details on his outfit would be appreciated.(Ideally with an account of your trip).
