I dont know how "Young" this guy is, but if he is young enough to save I might try to explain to him the importance of buying a liscense.It would be much more benificial to the sport to add another ethical hunter to our ranks than to just call the game warden. Not sure where I would draw the line, something like if the guy was a teenager I would try to talk to him, anything older and its time to call the warden. However, no matter how young if he refuses to listen it time to get him out of the woods. If he is past a saving age....I would have to agree with everyone else, make the call.
