Highwayman's Hitch relay
Ropes, Bar to tie off against
Scouts in Patrols (or teams or even numbers) give each other piggy back at must run up and the rider must tie on a piece of rope using a highwayman's hitch. When done they must run back to the start line and the next pair goes and does the same. The first patrol to complete is the winner.
Can also be used as part of a 4th July program explaining that cowboys in the wild west used to tie their horses up with a similar knot when they went into town and that it enabled them to have a quick get way
