Yep....age and life experiences does that. I used to live for deer season, whether bow or gun. I was driven to succeed and success was only determined by the size or the amount of the animal/animals in the back of the truck. Now when I go, I have a hard time pulling the trigger, even on bucks I would have wet my pants over in my youth. I have found the the camaraderie of deer camp/season is a unique experience on it's own. Looking back, the fun of the hunt and the joy of experiencing it with friends and family are what I remember more than the size of the horn taken that year. Nowadays my time in the stand is spent thinking about the years past, not what I hope is coming down the trail. I too have only a few years left in me. Every time I go out, I tell myself it might be the last and to enjoy it, even if I see nuttin' to shoot. The thrill of watching the dog work or whatever bird is working the tree next to me, warms my heart.
So go, whether you have a gun or not. I know from experience, that not having a firearm in your hand during a hunt does not feel the same. Don't mean you have to use the one you have. I have found over the years that using a handgun as a primary weapon widens the experience, while taking a lot of pressure off. When your weapon is only good for 30 yards, you can know yourself anything else you see would have been in the truck if you had your old dependable long-gun. You learn to hunt to impress yourself and not others.....and you learn that having the opportunity to just go out and enjoy the woods one more time is paramount.
