rope - 10 feet
beanbag or other soft weight, tied to end of rope.

Some reflection about how the scouts that got hit were treated by their own teammates and the other scouts might be useful.

Each patrol starts with 30 or 50 points.
Scouts form a circle about 18 feet in diameter.
Leader stands in the center with the rope.
Leader starts swinging the rope around at ground level and increases the length of the rope until it is out to the scouts.
People must jump over the rope as it swings by.
A scout hit by the rope loses 5 points for his patrol.
When a patrol's score reaches 0, all members of that patrol drop out of the circle.
The last patrol left wins.

Keep the rope between ground and knee level.
Have an alternate rope swinger ready in case one gets dizzy.

Alernative: When a scout is hit, he drops out of the circle. Last one left wins.
