If people aren't using game check, do you really think they would abide by tags? Hell no is the answer.
NM has a tag system , if you hunt you have a tag . Whether you are successful or not you must log in do a survey after season or you won't get a license and tags the next year. As a resident you don't tag the animal and are busted , you don't hunt next 3 years ( I think) , plus a hefty fine . If you're from out of state and do something stupid , you get a hefty fine and you ain't ever coming back.
Yeah and what the hell do they do to illegal's crossing their border. Priorities...
If one of those illegals shoots an Elk or some other critter , I imagine they'd be rough on him . If he killed a human , not so much.
"Why do you ask"?
Too many people spend money they don't have , on things they don't need, to impress people they don't know.
