On my first trip to South Africa in 1995 or so, work colleagues took me on a day trip into Kruger Park through the Kruger Gate, and lo and behold, one of our first sightings was of a roan antelope. There was a lot of arguing between the experts in the vehicle about whether it was a roan or a sable, and much exchanging of binoculars, but eventually there was consensus that because of the black and white face it must be a roan. They were amazed as they'd been going to the park for years and had never seen one. Thanks for sharing!
