I used to get the survey for every hunt I participated in. I wouldn't call it science. Did you hunt in Unit___? Did you hunt any other Unit? How many days did you hunt? Did you harvest an ____on your hunt? To what level did you feel crowded or uncrowded during your hunt? Were you satisfied with the experience?
Now for Moose and other hard to draw hunts, it is a different story...and it shows in the number of animals on the ground. In twenty years Moose went from rare (in most of the state) to being a constant pest in traditional elk habitats while elk are hard to find.
