the Four Rules of Safety as published by the Texas Parks & Wildlife Department.
Rule #1 is fairly simple and the most important of all safety rules: Keep The Gun Pointed in a safe direction. That would be don't point the gun at someone unless you intend to shoot them. TPWD reminds us, "Look around and see who or what might be in the line of fire." That's good advice.
Say you're out hunting some bird, maybe quail, for instance. If you see a bird and you want to shoot at it, look around and see who or what might be in the line of fire. It's a good idea not to shoot in the direction of your friends and fellow hunting buddies.
Rule #4 is equally important, I believe. Be Sure of Your Target and what lies beyond it! Right, always know what's beyond your target. Sometimes you might lose track of your hunting bodies; it's a good thing to check to make certain they're not on the other side of your target, 'cause your shot my take them out if you're not careful.
The Department goes on to reiterate, Never shoot at a sound or movement. Right; never. Know what you're shooting at.
These are good reminders for all of us, even those of us who have years of experience around firearms.
