Burger, Ryan, those are good points, and the website is informative. There won't be CCA around much longer, so my point is moot. I would point out that there are lots of things known to be bad for health that are not banned, and I don't want them banned. Don't protect me from my pleasures. I don't smoke but I don't want it banned, and taking nitrited meats up to cooking temperatures is probably not very smart either. But I eat bacon till Hell won't have it, and I don't want it banned. But I will always avoid any exposure to potential toxins if there are safer alternatives that don't jeopardize my pleasure centers. I'm better educated than I was this time yesterday, and I thank you both. In 6 hours I'm going to start a flight from Guam to Oklahoma to look in on the construction of my new pond. I feel like handing out cigars. Best regards, Tom
