ball for each patrol

Each patrol lines up in single file with their legs spread two or three feet apart.
Ball starts in the hands of the first scout in line.
On 'GO', the ball is sent down the tunnel between the legs of each scout to the last scout in line. It can be helped along the way by anyone, but it needs to pass through the legs of each scout.
The last scout picks up the ball and runs to the front of the patrol line and sends the ball through the tunnel again.

The first patrol having the first scout back at the front of the line, wins.

You may need to have some scouts go twice to even out the number of trips through the tunnel.
You may add a rule that causes the ball to start its trip through the tunnel from the beginning again if it breaks out of the tunnel.
