The best deer hunting tool / skill I've developed is learning to filet on the spot of Kill. I take everything including heart and liver. Never, even for the biggest bucks more than 60 lbs....................... Sure my 6'5" 205lbs affords me the torque to get them in the tree easy, but anyone can do this, even halfway off the ground. In a backpack a deer is easier to deal with than on a sled, or one of those rickshaws. Oh, the real key is to stay in shape! The human body changes very little year to year, from age 25 to 75 for those who take care of themselves. Last year I shot a nice buck
less than 400 meters from my car. I still fileted. It was still easier.
I love hunting like I was 18, but hopefully with a little more experience.
Seems to me I have seen videos on this skill....
