Hold off on the sharp knife for little bit. [Yano, I get "queasy" when I see much of my blood, but other people�s blood doesn�t bother me much. Weird, eh?] [Oh bye-da-bye, I didn�t win the bar bet on "Ground Hog Day". I didn�t loose it either. T

This is brutal. I think we should call a truce. Mike has very good points and his quotations from the EPA letter are fact. If there isn't a competitor of Bill's who hasn't seen this letter I'd be surprised. We could go on and on about this and th
