Cow Bingo: Is this a thing?

I swear to god my mum is making this up.

She says that she and her neighbours, in rural Vermont, on the 4th of July, for entertainment purposes, they play cow bingo.

She marks off her lawn into squares. They all pick one. They let a cow loose on the property. Whosever square the cow poops on, they win.

This has got to be a lie. Has anyone else on this board ever heard of such a thing?

sure it is

Yes, it's done at county fairs in all the states I've ever lived in (Indiana, New York, Michigan, North Carolina, Arizona, Washington).

Pig-racing, I have heard of. Cow Bingo, that's a new one on me.
