In cold conditions cotton is death. Do not use cotton under wear. No matter how good a woodsman you are bring at least two compasses. GPSes are great but batteries die. Besides when the clouds drop down below the mountain tops you will want to know where camp is. A compass will verify your first compass and your GPS. Bring a good head lamp, great for skinning and travel at night back to camp. Seems like I always kill an elk right before dark.
Time spent hunting is not deducted from one's lifetime.
