Free: Contests & Raffles.
I just met a guy who openly admitted he might do just that for late deer. Said he never tagged his buck and never got checked so still has a tag he can use. First time meeting him too - and no he wasn't a gamey.
with the amount of deer/elk remains i've found throughout the year when i'm out fishing or dinking around in the woods, i'd say i wouldn't be surprised if the local hill jacks and brush pickers take more out of season than hunters do in-season.
