To expound a little further on the topic, I'd never pass a 4-year-old in hopes he becomes a 5-year-old. That's just nuts for 80 acres in a heavily hunted area. I also plan to pass the 2.5s that show something more than just basic genetics. My new philosophy is to hunt hard until hun season and hold myself to 4.5 or older. Come gun season, I'm flipping over to Mr. "Fill my buck tag every season" guy. They're made of meat and other than having fun, putting meat in the freezer/jar is what matters most these days. I've had enough tag soup to last a lifetime.
Small buck "grip and grins" to come from this guy!
