Yep, I'm with you, James. That's exactly what crossed my mind. If the payoff is as high as is claimed, then the local gov or private sector will keep it going. But to be honest with you, those sorts of estimates are suspect in my mind.

"Per Key, the trout fisheries value is almost equal to the value of electricity and flood control combined." Yeah, but remove all 3 and see which ones are really important.
