Grid Reference Sheet
Divide into Patrols or even teams.
Scouts will race up against each other and the leader calls a number from their sheet.
Scouts will look up this number on thier sheet and must then find the coresponding grid reference on the map.
The first Scout to identify the point of interest at that location is the winner.
