Bovine-Bingo is a "country" gambling sport, seen at county fairs, etc., and often used for fundraising. Tickets are sold for each of 100 or even more squares marked by chalk lines in a pipe-corral which also functions as the bleachers. It cost $5 per square at Mule Days in Bishop CA 15 years ago. You do not know where your square is until after you buy it, and then find the markers or map if you can. Your square is picked at random. The cow is led in, and the "fun" begins. The crowd roars, cheers, and jeers like a Hee-Haw skit. Once Bessie un-asses her cow-pie, the referee and Line Judge rush in with a scale and shovels, in case Bessie laid it on the line.
