The way we hunted elephant along the Tana River in NE Kenya was to let most of the air out of the tires of the Land Cruiser and drive down the dry river bed until we came to a spot where the elephant had dug down to water with their tusks. Then we would dismount and examine the tracks. If they were big enough and smooth enough (old elephants' feet have the tread worn off them like old tires), then we would strike out after the old gentleman on foot. Inevitably we would finally locate a very old elephant with two ivory toothpicks sticking out of his head, and turn and walk resignedly back to the vehicle. Two solid weeks of this in 90 degree heat does great things for your waistline. This was the result on the final day: http://www.frappr.com/?a=viewphoto&id=3823381&pid=7017140&myphotos=1
