Whenever I see kiddie swings, I have the urge to swing on them. Man, I haven't been on a swing for 5 years, when we were in Okinawa, at White Beach Naval Station just as the sun was going down....sigh...

Did anyone ever do the Swing Longjump? You'd swing as high as you could, and at the apex of the arc, you jump off, the winner being her/him who jumped farthest. Note--this only works on playgrounds covered in sand!
