Jim,
I won't get into politics again, but the fact that the EPA was formed by Nixon shows how far right the country has drifted from the 1960's. I often say that Clinton was more of a Republican than Nixon based on some of the legislation they each passed.
I have to ask, but with Mercury and DDT long banned, I would say that throwing those things into the the mix as an argument against golf courses is not exactly fair, is it? And, given the regulations on golf course maintenance areas, I think your example, together with the "not the lone example" statement isn't fair either.
You make it sound like it happens all the time, so where else has that happened? If its not the lone example, please enlighten me, because I haven't heard of any other example of a golf course sale being negated for similar reasons.
