I distinctly remember a few years back whilst camping at a State Park( I believe it was in Mn but maybe not), posters in the bathrooms warning us of the dangers of lead and lead poisoning of birds. I also recall many moons before that even, that those drinking glasses that McD's used to sell., collector drinking glasses, buy the whole set of 6 or whatever they were peddling at the time, that it was found that there was extremely low amounts of lead in the colored paint on outside of glass so they quit selling them. While it is true some of my wardrobe may be mistaken for a wal mart shopper, I certainly knew enough that I should drink out of those glasses versus eating them.
