Marc, when my brother and SIL were there, they had a canoe thing from the hotel with a guy named Colin... booked him through the hotel and loved it. Colin is a Zimbabwe native now in Zambia. It is a canoe thing, and quite scary to me, as Rhinos can go underwater for so many minutes and then surface. But I plan to do it. I think Joe has his website, but I don't think this guy is an e-mail sort of person. I'll ask Robin if she can pass along pictures from their time with him.
