I am also tired of the public land argument. The federal land belongs to every citizen of the U.S.A. The animals on that federal land belong to the state.
If you kill a animal without a license the state goes after you not the federal goverment.
The state manages the animals, the state issues licenses, the state issues fines. These are state owned animals.
If you want to enjoy federal land? Get off you a$$ and go for a hike in the national forest. Just don't kill an animal without the proper license or the state will come after you.
