Sometimes the wild ones just ignore the tame ones, sometimes they're aggressive and although I've no personal experience I'm told the odd bull in musth may get a bit amorous! - There's a guy called Randall Jay Moore who has a camp in the Okavango Delta in Botswana called Abu's Camp. Abu's dead now but was a real Elephant movie star and amongtst his many appearances was in White Hunter Black Heart.

Anyway, Randall Jay Moore wrote a fabulous but obscenely expensive book called "Elephants for Africa" and it's well worth reading - esp if you don't have to buy it yourself! He talks extensively about his Elephant back safaris in it and the photographs will take your breath away.

More affordable but also excellent & very informative reading are the following:

Silent Thunder by Katy Payne
When Elephants weep by Jeffrey Masson
Africa's Elephants by Martin Meredith
Coming of Age with Elephants by Joyce Poole
Mahohoba by Ron Thompson
Wildlife Wars by Richard Leakey

They all have different points of view, some you might not agree with, but there's something to learn from all of them.

I personally believe that Elephants are in a class and catagory of their own and I think it's such a shame that so many hunters simply have no idea about their social structures etc before they hunt them. If they had a deeper knowledge of the species they would enjoy and appreciate the hunt so much more...........
