Copper Wire

After having dug to a depth of 10 feet last year, New York scientists found traces of copper wire dating back 100 years and came to the conclusion that their ancestors already had a telephone network more than 100 years ago.
Not to be outdone by the New Yorkers, a California archaeologist dug to a depth of 20 feet and shortly after, a story in the LA Times read: "California archaeologists' discovery of 200 year old copper wire, have concluded that their ancestors already had an advanced high-tech communications network a hundred years earlier than the New Yorkers."
One week later. A local newspaper in Alabama reported the following:
"After digging as deep as 30 feet in his pasture near Smiths Station, AL, Bubba, a self-taught archaeologist, reported that he found absolutely nothing. Bubba has therefore concluded that 300 years ago, Alabama had already gone wireless."
