JCO I never worry about things, but I do consider them. I do have all of the specs. and materials list that are accepted and I intend to build my system accordingly. But, this is in my area and I am not really convinced it will be worth while to get OC here. I know probably in some areas there would be a better market for OC produce and was hoping to hear from some folks in different parts of the country about this. Even if they are not selling commercially, they may have noticed if OC produce sells in their area or just sits on the shelf? All good things to pay attention to and think about.
