Having no kids, I don't have a "dog" in this discussion.
However, from my personal experience, its the adults that either cause the problems or allow them to occur :(

The two worse incidents that I ever experienced was a group of adults that were camped across Jean Lake from me. They were obviously imbibing heavily and long after dark were yelling and carrying on at the top of their lungs. The worst part was they had a "lady" with them who laughed like a African Hyena at every thing that was said.  I thought about paddling over, but knew it would be just a exercise in frustration on my part. I fell to sleep way after midnight and dreamed my revenge ;)
A .308 sniper round from 1/2 mile away finally silenced the Hyena ;D

The other incident involved some boy scouts and their leaders. They were coming across the portage from Conk into Jean lk. They could be heard way before I saw them. Yelling and talking at the top of their lungs. When I got to the Conk side, they had gear and canoes scattered all over the take-out. I dropped my gear in the woods and walked down to see what was going on?

When I mentioned to one of the leaders how LOUD they were and did he realize how sound carried, he told me that the wilderness was the place for boys to be boys, and that meant being loud and rude! I asked them how they were going to learn a respectful wilderness ethic, IF the leaders didn't teach it too them? He gave me a dirty look and I walked back and let them clear out.

 I give kudos to anyone who takes kids or newbies into a wilderness setting as long as they teach them the right way and clean up after themselves. Unfortunately age doesn't guarantee good behavior or self control.
