Do you do your hunting with a camera or your eyes? If the latter, you already buy a license. If the former, you should do the same.
North America's wild places are supported in part by fees and licenses paid by sportsmen.
If you love public land, if you support your state DNR, do your part to help keep North America the wild continent that it is. Buy a fishing license, even if you don't know a walleye from a perch. Buy a hunting license, even if the only hunting you do is with your senses.
We've got coyotes living in the city. We've got wolves venturing out of their established habitat. Those are the good problems to have. They're not that lucky in Europe. The difference is the North American model of wildlife conservation.
It's paid for by taxes on firearms, ammunition, and licenses charged to anglers and hunters. The tax money is distributed to the states based on a formula dependent upon the number of licensed hunters in the state. Even if you don't own a gun or a bow, you can still support wildlife by buying a license.
Be kind to your web-footed friends. Buy a duck stamp.
Keep America wild. Buy a hunting license.
