I was up in a tree stand one time and 5 feet away in the tree next to me a squirrel climbed down to my eye level and began barking.   Trying to be a good hunter, I didn't move and tried to ignore him, well, after 20 minutes of non stop barking, and surely alerting every deer within a mile of my position, I turned him into a spray of red mist.  No, it wasn't right to do that, but I felt better!   I somehow attract squirrels, I don't get it, they love me or something? Lol
