Iron Triangle 
(Ditch) 
Materials:      The reeve will need a watch. Rope or tape to better define the triangle would be nice. 

Set-Up:      Divide the populace into three equal teams 

Object:      There is a large triangle on a field, each leg at least 15 yards long. Three teams fight for possession of it. At the end of 15 minutes (reeve calls "time"), the team with the most players inside the triangle wins. Each team may only enter from one side of the triangle and no other. Teams may only fight each other within the triangle. Repeat until all are satisfied.
