RE: Flintlocks and hunting blinds
It was my buddy's farm. I about cried laughing watching this 6'8" 300+ pound farmer out there jumping around, cussing, andslapping the hay with is hat. So I ran over there and mentioned the snow on the ground... We then piled snow all over the top of the hay, and he did later shoot a young doe at about 30 yards with no cooking fire.
Actually a hay bale is nice to hunt from. They are warm, comfortable, and its basically a bench rest for when you have to shoot. I've done some long range busting out of them with modern rifles.
