Frank's incredibly dangerous game.

My friend Frank McGaster and I used to play this game where we'd throw circular saw blades at each other like frisbees.  We're lucky neither of us either got hurt.  We didn't realize how dangerous it was until Frank accidentally cut down a tree while throwing a saw blade at me.  I don't think I should even be saying anything, because I don't want kids to think it's OK to do that stuff, but I also think I should spread the word so people can learn from our mistakes.
