I was on a differant thread and posted about washers. We play washers in Souther Illinois alot. Its kinda our thing.
Some may call it redneck horse shoes or what ever.
I would think this would be a great thing for folks on boats.
Now, I would say play it while on a beach or in a port area. This game is best played with a cold beverage in one hand.
All You need is 6- 2.5 inch washers and a can. I prefer a Box. Very easy to make.
I will include some links for your browsing.
What games do you play? I mean you have to do something. I have never sailed upto a island. I would think after sitting there for a week. One would get a little board. What do you do?
