It's all good Preach
I don't loose any sleep over it

I predict some will say...."canoes and people bring problems into our parks, lets keep them out".  In fact, it's well documented that all lead hooks are brought in by canoeists.  All overfishing is done by canoeists.  All campsite overuse and erosioin are done by canoeists.  In fact it's well documented that live bait (non-indigenous) is brought in by canoeists.

....So outlaw canoeists in the Q.  As you say, the park does not exist to provide a profit.  In your own words...the "park exists to preserve the ecology".  Keep the dam people out and it's "problem solved". ;)
