Answers generally vary.
How? For conservation. Because there is no better feeling in the world than shooting a gun. The deer I harvest go to good use rather than being turned into a venison smoothie by an 18 wheeler. Bambi was a movie and has no basis in reality. Have you ever heard a deer talk? No?
Yes, ducks are cute. But they taste even better.
Why? Is that even a question? Camo is awesome; it goes with everything and if I wear it all the time, I'm always ready to hunt.
How? Well, dear, delusional friend, getting up early, staying out late, losing sleep and becoming a recluse from society for months on end each affords me a unique perspective that not many are blessed to see.
Once I answer, I'm generally met with a vague stare. If I could effectively answer this question maybe my interrogator would finally understand why I adore my time in the woods so much....
I hunt because...
there are stunning sunsets which make the entire, unfruitful day worth every second,
there are colors so vibrant that make you wonder why God painted them on the wings of elusive waterfowl,
there are mornings so cold that a sunflower heater for one turns into a community heat immersion system,
it creates bonds that last a lifetime,
there is no clearer, quieter surrounding than a half hour before sunrise,
and there are moments that take your breath away.
Yes my friends, there is so much beauty to be had in the world that is lost by those who are too busy to notice. Hunting allows me to feel nature in its most ancient and real form. Absent from the hustle and bustle of the modern age with the cell phones, TV's, addiction to celebrities, and all the other junk that clutters life; hunting purges its minions of all confining things.
I feel most alive when I hunt.
Maybe that will be my new answer.
