I haven't heard from Parks at all, even to say that they are checking it out. If Parks was in the private sector it'd be out of business. Why an arm of the government can be so unresponsive to a taxpayer is beyond me. Low standards, anyone?
Regarding trash, litter, illegal dumping, etc, there must be public policy to address the issue. Historically it is the only thing that gets at the root of the problem. And believe me, I volunteer a lot and pick up plenty of litter on my own. But the vehicle for lasting change, the kind that bends the curve, must be from the government.
