I highly recommend a visit to The Sterling Hill Mining Museum in Ogdensburg, NJ . . . it is the self-proclaimed "Fluorescent Mineral Capital of the World" and you will not be disappointed in this regard . . . the museum (Zobel Exhibit Hall) contains a startling array of valuable minerals, fossils, and mining equipment-- in fact, it was recently burgled-- and the pièce de résistance is a giant wooden periodic table with cubbyholes containing samples, ore and examples of every element (there should be one of these in every science class . . . but the guy who built it said it contains 25,000 dollars worth of stuff) and when you do journey down into the historical Sterling Hill Zinc Mine, perhaps you'll be lucky enough to have an older gentleman named Bob as your guide . . . he calls the men "Ace" and the women "Sweets" and speaks in staccato sentences that begin with information about the mine but end with anecdotal non sequiturs about twenty dollar bills and driver's licenses, motel rooms and electrical outlets, and the importance of a good dentist . . . he's also not afraid to tell a joke or two (e.g. what side of a cow has the most hair? the outside) and every time someone sneezed he high-fived their snot coated hand and said, "God bless you and God bless me," and, if you are still not understanding the value of having a guide with dementia, remember that it's a two hour tour deep into the bowels of the earth, so having Bob as a guide only adds to the excitement, as you're not sure if you will ever return to the surface again.
