MD...

I know all about hunting in the cold Bud. The flintlock season here in PA can be very challenging as far as weather's concerned. I have hunted in weather from -10 to near 60 degrees in January. I've seen the weather change from sunny and clear to rain, freezing rain, sleet, and then snow in a matter of hours. I got in a stand early one overcast New Year's eve morning and within a half hour, it began to snow big, wet, snowflakes the size of a quarter.
I had a cow's knee on my lock but I had a heck of a time trying to keep the snow from building up on the barrel and covering the sights. Well lo and behold about a half hour after it started (and was still snowing), here come the deer, headed right towards me.
One big ol' doe came right up within 40 yards and I tried to clear my sights enough to see them before removing the cow's knee but no dice... she caught my movement and peeled out!
The coldest day I ever shot a deer with a flintlock it was -7 when I left the house at daybreak. About a half hour later, a young deer came out of the neighbor's cornfield and traveled about 150 yards straight to me and offered itself as a sacrificial lamb so I obliged!! Damn, I was happy that hunt ended early!!
