As a corollary or extension of that idea. There are reasons why elk go where they go and do what they do. We may not know WHY the elk show up at the same place over and over again, but there is some reason. So . . . hunting the same area over time you begin to see repeating behaviors. That knowledge is like money in your elk hunting bank. What is interesting is that these reasons persist even when elk die and are replaced by other elk. The same factors that lead the elk to go where they go and do what they do may still be operative 20 years from now, and hence the elk will be doing the same things at the same time. Of course, sometimes something changes the environment so the factors are altered.
