I know this doesnt really belong here, but i've heard it on my way to the deerstand several times and i just heard it again tonight. Every once in a while i'll hear this aweful sound. It's like bone chilling kind of hair on the back of your neck kind of sound. It's always at night, and it goes for 1-2 minutes in bursts. it's always the same sound. I dont even know how to explain it.Somthing like Keeeeee wappp but very loud and high pitched. any ideas? I have to turn around and go home when i hear it because it's so scary, even with a weapon.
