It's not Churchill Downs but it certainly causes people to flock together to enjoy the bizarre sport of racing these large, stupid flightless birds. Apparently originating in South Africa early in the 20th century, this entertaining competition is currently enjoying a renaissance worldwide. The grotesque poulty line up on the starting line as the riders struggle to mount their molting steeds. When the official starter removes the ostrich's hoods, to signal the beginning, the birds careen wildly away from the line in no particular direction. Depending on the rider's weight, these flailing fowl can reach speeds up to 50 mph. The winning ostrich gets to live while the losers wind up feeding the exuberent spectators. Favorite souvenirs carried away from the events are Boas and eggs, each egg large enough to make an omelet for 20.
