Minesweeper:

This would be a fun orienteering game that can be played in a park. The gold coins are laid out in a pattern which changes each time the game is played. The contestents would be given true bearings to each coin from the start point. There will be numbers on the bottoms of the coins.

The task will be to find all the coins in the shortest time and the scorekeeper would log the number on the coins the contestent finds.

To make it interesting, two duplicate sets would be laid out. One if they forgot to correct variation. Another if they corrected the wrong way.

The winner will have gotten ALL the correct coins in the shortest time. (No credit if you "step on a mine.")
The contestant will have 30 minutes to prepare their plan of attack.

There will be a map and compass class and a GPS only class.
