This picture was sent in by Eric. He explains: "We like to play horseshoes and drink beer at my friend's house, but we got tired of running inside to pee. For our comfort, he rigged up this old sink in his garage to serve as a urinal. It drains into a gravel-filled underground hole outside. You flush using the little white plastic pail, which is dipped into the big pail next to it. Note the mirror, towel and "please flush" sign for our convenience."
