Fun is well you know just having Fun!! It will be different things to me on different days or even depending on what area I'm hunting.
Some days it's just busting a Doe other days it would be taking a P&Y Buck. I always set my goals according to the time of year and area I'm hunting.
I enjoy the Kill and would not hunt without it. I never set my goals to the point that I take the fun out for the entire year.
If someone enjoys sitting in a tree for hours, days, weeks, and months without shooting something then more power to them. It's just not Fun to me
