During our weekend in Montana, we had the option to fly on two different swings. The first was your standard swing of two ropes attached to board. But the one everyone loved was the disk swing. This was just a circle of wood with a hole in the center for the rope. The rope was knotted securely under the swing and then tied even more securely to a branch at least 40 feet in the air.

At first, students took turns on the swing, pushing each other high in the air and squealing. But then they developed a new technique.

Two people got on the swing — looking like a seated Push-Me-Pull-You. Then three or four folks on the ground pushed the two swingers in a huge circle or grabbed onto the end of the rope and give them a running surge of velocity! Talk about a sudden feeling of death as ground rushes beneath and trees come too close!
