It's sad that we have kids displaying such disrespect coming up through our ranks. It's not my nature to "call the law" over every legal infraction I encounter in life, game laws or otherwise...particularly if I did not witness anything. Since the kid is young and probably never had a proper introduction to hunting, I'd sieze the opportunity to give him a little mentoring and instill some hunting values with him. While doing such, I'd also give him a stern warning that if you DO find him hunting without a license, there will be reprocussions.

For now, "calling the warden" would serve little else than to put a sour taste in his mouth, likely prompting him to thumb his nose even more at game laws out of spite. Certainly, he won't develop any set of values or respect from it. (BTW, I don't consider fear to be a form of respect.) But if you put forth a personal effort with him, you've got a chance that he may just be appreciative, develop a decent set of values, and fall into line. If you're lucky, he may even stick with hunting long after we're gone.
