There was some talk about how much fun it would be to go to a lake for the next reunion. How about Bear Lake?

There weren't any group sites near Lake Powell. This one is by a lake in Arizona. It sounds really nice. It claims to have toilets and showers. It is near Springerville, AZ which is near St. Johns. I thought that might be fun.

Or how about going to the real beach in California?
