Now that is a new one on me: cow patty bingo.
We have lots of kinds of bingo, but never seen that
one: how's it work (I am almost afraid to ask)?
Mark off a field into a grid (I've usually seen it on the school's football field--the coaches LOVE that!), letter or number the squares of the grid. People then "buy" a square/squares. Turn a cow/bull loose on the field. Let nature take it's course, and the first "square" of the grid that was bought in which a patty drops is the winner....usually receiving a percentage of the money brought in by people buying a chance on a square or receiving a predetermined prize.
Not exactly the height of excitement, and not exactly a spectator favorite.
I personally liked the "Car Drop" that a local group used to do in my hometown. The lake would freeze up every winter. The group would put an old clunker out on the ice and people would, for a price, tell the date and time in which the car would drop through the ice into the lake at thaw.
Strangely enough, the state EPA put a stop to that...for some reason they didn't like the idea of old cars sitting at the bottom of the lake.
