The group splits up into two sub-groups which we will call A and B.
Group A leaves 5 to 10 minutes before Group B and must leave clues behind ( footprints, marks, arrows, codes, pieces of paper, etc….).
They must then camouflage and set up an ambush for group B.
Group B leaves and follows the footprints and clues left by group A and tries to discover the ambush site.
During the ambush the groups face each other in mock combat (stealing of scarves, indian wrestling, etc…).
The meeting of the two groups could also result in the yelling of, “AMBUSH” and a race back to home base again.
