Build a bridge across a small river using Pioneering Poles, Rope and some willing Scouts
Pioneering Poles (4 large, 2 Medium, 4 small), Lashing Rope, 1 rope for bridge (or lorry straps), 1 rope for handrails, Sisal for verticals, hawsers or ratchets to tighten rope/straps
The bridge will require good ground anchors at both ends - trees are good! Bridge will consist of two A frames rope for the bridge and two hand rails. Suggest you look up Monkey Bridge on the internet for instructions - as a diagram is worth a thousand words written here.
