I see the problem and it's never "our" problem
I may be wrong, but we seem to see one sided cases "legal" cases, too often. The opposition is always wrong.
Well, how did a "teenaged kid" even find your location? Was he using a gps to get him into your area, a deep dark hidden place.
You never indicated if it was private, and how many yards you were from a road or trail. Experienced hunters should know that the closer we hunt to a road or trail, the better the chance of getting disturbed by somebody.
And if anyone is hunting close to a trail or road, you'll have to examine why you are hunting close to a road or trail. Not just examine why you got disturbed.
