Fishing for Mousetraps Game 
This Game is meant for Boy Scouts.
Decide for yourself if it is appropriate for your younger scouts or not.
Required:
4 4ft ropes per patrol
4 5-6ft staffs per patrol (broom handle size)
1 mousetrap per patrol
Instructions:
Place the loaded mousetrap about 12 feet out from a starting line (the shore).
Each patrol tries to be first to retrieve their mousetrap.
They may decide to just tie the ropes together and toss it out, but chances are this will spring the trap without having it catch on the rope.
The hope is that they will tie the poles together and dangle the last rope from the end to spring the trap. You may spell out this rule if needed.
