tommy,
I'm sure you'll get many responses... this is a common discussion here. search 'environment' or 'sustainability' for a few interesting discussions.
you're right, golf courses have taken strides in protecting and (perhaps more importantly) enhancing the environment, and there is still potential to do more. As for the state senator, it sounds like he's towing the all too familiar (and in some part, misinformed) public line... i would doubt highly that he has any idea of where the proposed site even sits in the watershed....
