The Western Melbourne Metropolitan Orienteering Series event using the Airport West map on Tuesday, 8 December 2015 is one of several events run on Tuesday evenings through the summer.
Participants each receive a map with 20-25 pre-marked control points, and a card which is used to record the controls located. Controls are positioned on features such as light poles, fences, or trees. All participants start together, and must return to the finish within a designated time, or after locating a designated number of controls. It's up to you to decide which controls to go to.
