The hardest thing for me to do is sitting in one spot for long periods of time. I don't mind sitting and glassing, but not for more than an hour at a time.
I grew up archery hunting and still hunting is probably my favorite way to hunt. I have never hunted out of a tree stand and do not know how some of you can watch a critter come by out of range and not go after him.
I adapt very well to any environment and do not have a problem diving into any type of country. As far as gear goes, I guess I could say that I have advanced greatly. In my younger years I never had a day pack and never even carried water with me. Now I pack around 25-30 pounds of gear even when I am just antler hunting.
