Equipment: Tie several pieces of rope of varying thicknesses together, using several different knots (square, sheetbend, bowline, two half-hitches, taut-line hitch). Tie one end of rope to one tree with clove, the other end to another tree with taut-line hitch.
Action: Patrol is told to walk along rope from tree to tree and back again, silently, to observe and remember (approximately 2 minutes). Patrol then goes into huddle to come up with list of knots seen (including knots around trees) in right order.
Scoring: Patrol with best list wins. Trick question for extra points: How many ropes used?
