This picture was sent in by C&MH. They write: "Attached is a picture I took a couple of weeks ago. These urinals are at a rest stop in Serengeti National Park in Tanzania. All such installations were scrupulously clean. Water for flushing is in a tank on the roof, brought in by truck. The Serengeti is an enormous plain, mostly grassy, with vast numbers of wild grazing animals – zebras, cape buffalos, gazelles, etc., and the lions and cheetas that prey on them."
