1. The 4th Commandment of Firearm Safety says: "Be sure of your target and what's beyond it. You can't stop a shot in mid-air, so don't fire unless you know exactly where your shot is going and what it will strike" (Remington Arms)
2. The outdoorsman's pledge: I will leave the woods in the same condition (or better) as when I came in. (Better yet - leave no trace).
Those who can't follow these simple rules, shouldn't be taking advantage of our public lands and natural resources.
