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
 more than 100 years ago.

 Not to be outdone by the  New Yorkers, in the weeks that followed, a
 California archaeologist  dug to a depth of 20 feet, and shortly
after, A
 story in the LA  Times read: "California archaeologists,
finding of 200
 year old  copper wire, have concluded that their ancestors already
had an
 advanced high-tech communications network a hundred years earlier
 the New Yorkers"

 One week later. A local newspaper  in Tennessee reported  the
 "After digging as deep as 30 feet in his pasture  near
Cookeville, Tennessee ,
 Bubba,  a self-taught archaeologist, reported that he found
 nothing. Bubba has therefore concluded that 300 years  ago,
 had already gone wireless".

 Just makes  you proud to live in Tennessee don’t it.
