The black hole

One of our 'training exercises' was to keep from falling in the 'black hole', we had to get across on tire swings without touching the ground. If anyone touched the ground, the whole group had to start over. Our group was almost all over in record time, when the next to last guy, Josuè touched the ground. So we ALL had to do it again. I think I did it a total of three times. After that everyone just kept falling. We never ended up doing it. Everyone got across at one time or another, but it didn't count. Oh well.
