Thanks for the Bireley's link, wow! That's the one! And to return the favor, since you also live at the coast, here's a link from a fascinating article in a recent Smithsonian about a man who conducts scientific research by assembling data from the flotsam and jetsam accumulated by beachcombers around the world...soda bottles are a favorite item. Anybody who lives at the coast should enjoy this one.
