What cooperation? I get nothing from NYC of any value. They steal my Adirondack water and air. Their "water quality police" protect THEIR water in OUR local reservoirs by giving us speeding tickets because supposedly our speeding degrades "their" water. And I pay their salaries through my taxes.
All I get from NYC is tv and the Yankees. I do not need their hospitals or shows or museums, and my own college suits me just fine.
