On thing to remember is that here in Colorado since a law was passed a few years ago you have to eat the marmmots that you shoot. It is a wacky law but I think that the only animal that you are not required to salvage for the meat is a coyote.
We did have a funny encounter with some while backpacking. My girlfriend was walking on the trail in front of me. Well, it was getting dark so the visibility was low. Anyway, I heard what sounded like a whistle. I looked around and didn't see anything. Instantly, my girlfriend said I didn't have to whistle to get her attention. I replied I didn't whistle. A few steps later, another whistle. She turns to ask me what I needed. I said nothing. She's getting annoyed at this point. But as she is turned looking at me, another whistle sounds off from the distance. I said, It wasn't me, now do you believe me? She started laughing and asked what it was. At this point, we couldn't see a 100 yds, so there was no way for me to explain the whistles. The next day we figured out where the sound was initiatiing. It was funny while it lasted.
From the books that I have read, there is a lot of importance in knowing every nook and cranny of your hunting territory as well as the animal that you are hunting.
