If they see this map at the lodge, and three or four of the members are already out, they know to avoid that area and pick another place to hunt. Club members picked up the idea while visiting a hunting lodge that used maps of its property as place mats during meals. The lodge also provided maps for its hunters to carry into the field. Warrior Hunting Club took it one step further by creating a large color-coded map, laminating it and hanging it on a wall in the club's lodge. When the land changes, especially because of logging, the members print a new map to mark the differences.
Members use erasable felt-tip pens to mark their position for the day.
Then they erase the map at the end of the day. It's a club rule. The map tells us where an individual is in case we need to go looking for him. Hunters can learn from studying how many deer have been harvested in a particular season, but also from knowing where and when those deer were taken. That lets us know whether we can make other areas more productive by planting.
