I've seen a photo of someone riding an Indian rhino before( Michaela Dennis/Whipsnade's Mohan 1950's- features on cover of a book I think 'Ride a Rhino') while more recently David Gill of former South Lakes fame courted some bad publicity from a similar photo of himself atop a White rhino. But haven't seen a black one like this before.
