We played an old favorite game where you throw a ball up and everybody runs until you get control of it. Then you try to knock people out. I could NOT think of the name of the game. Deanne just reminded me that it's called Spud. (Showing my age, I guess.)
We went fishing. We had an epic water balloon fight. We played cards. I sang and played my guitar, to the bemusement of several (my taste has been formed by years of Scout camp and backcountry campfires). All in all, it was a great time.
