Oh believe me, yes they do. I have a buddy with a mullet who plays and lives in Arkansas and it's basically something to occupy your time while you BBQ and drink beer with friends. He even has a side business making customized boards.
That's the draw, something with a simple concept that you can get ultra competitive with. It's fully portable and doesn't require heavy horseshoes or driving a steak into the ground and setting up a proper pit. You just pull the boards from the bed of your truck or trunk of your car, measure off the distance and get down to work. That's the thing with cornhole is it's simplicity will allow anyone to play without fear of not understanding the rules.
Cornhole isn't the draw, but it's a nice way to meet new people. (Oh that sounds bad lol)
Remember carnival games? The toss the bag in the clown's mouth still exists, you never see the gaffy pool table setup anymore like you used to. Imagine working at a carnival and trying to set up a pool table at each stop. Yikes.
