Flushcut: I know you were just funnin. Besides, you would really need to be a hardcore mental case if you saved some agent orange for 40 years.
I don't think you could buy any now, even if you advertised your desire on ebay & craig's list.
Poor agent orange always got bad press; it wasn't the product's fault. It was the folks making it that turned it into a toxic brew. Many years ago, I could buy "turf ester" that was essentially the purified active ingredient in agent orange. It worked really well for tough lawn weeds, and the price was pretty good, too.
