I remember the first time I went deer hunting.... sat in a tree for 3 hours and it was in the low 20's, about 80% humidity and 25 mph north winds and we were in the woods long before sun up. Yah, it was FUN!
Enjoy your time in the woods. Usually a lot to see it you pay attention. My favorite thing (next to a large buck in my crosshairs) is the sound of birds wings flapping as they fly near you.
