This is a great thread. I'll try to add.
First, its about cultivating that sense of adventure inside of you that makes you a man. Not to disrespect women, but for me personally, walking out to my stand in the dark, camo'ed up, bow in hand creates an undescribable feeling.
Second, its already been mentioned, but seeing, feeling, hearing and smelling all the natural wonders God has created is just unbelievable. The other night as darkness put its death grip ending another day, I gazed at the black silouettes of tamaracks against the pinks, yellows and blues of what was left of the lights in the western sky. I love that moment - the solitude, and a thought went through my head - how sad that so many people were inside watching television that they missed this moment.
Third, the solitude. The serene quiet of the earth before humans wake up and wreck it. No vehicular sounds, no screaming kids, no lawn mowers, no gunshots. Just the slight sound of the breeze drifting through the treetops and the rustle of leaves and grass as the small creatures search for their breakfast.
Fourth - its a personal challenge. You can't blame any mistakes on your teammates, nor is anyone else there to steal any glory. You get out of it what you put into it - nothing more, nothing less. Everything is in your control and with the right input, you'll get your expected outcome. If not this time, maybe next.
Fifth - the challenge. Its takes effort to hunt. No matter your skill level, there's something in hunting for you.
Sixth- The thrill. Its all about anticipation and the unexpected. You just never know what you're going to see. And a slow night can get exciting in an instant. And no matter how many times you do it, getting a deer is always adds excitement.
Lastly - the stories. What would bowhunting be if you didn't have stories to share. Ones that got away, successful hunts, near misses, blunders, etc. My brother and I talk after every hunt, even if its just a quick call to say "didn't see anything." More often than not, there's something more to be said, and that makes it all more worth it.
Here's to many more seasons to all of you fellow bowhunters!
