Same here. However last year I was on a father/son trip., and one of the boys brought swords made from PVC pipe wrapped in foam. Safe right? Well, I was standing on the sandbar talking to one of the dads. The boys had dug a deep hole in the sand. I watched as the boy in the hole threw a sword like a spear, handle first, straight at my son's forehead. I immediately thought, "that didn't look good." In a few seconds I hear my older son scream, "DADDY!" I ran over and blood is pouring out of his forehead. Thankfully, I had butterfly strips in the first aid kit. We were 10 miles down river with 30 miles to go. There are no other takeout points. The butterfly strips worked pretty good. He wasn't able to swim, but he was ok.
