Copper wire.

[donyang1971]

mpter having dug to a depth of 10 feet last year, British scientists found
traces of copper wire dating back 200 years and came to the conclusion that
their ancestors already had a telephone network more than 150 years ago.

Not to be outdone by the Brit's, in the weeks that followed, an American
archaeologist dug to a depth of 20 feet, and shortly mpter, a story published in the New York Times:
"American archaeologists, finding traces of 250-year-old copper wire, have concluded that their
ancestors already had an advanced high-tech communications network 50 years earlier than the British".

One week later, Canadian Dept of Mines and Resources in Northern Canada reviewed the following:
"mpter digging as deep as 30 feet in Northern Canada in the Ontario region of Thunder Bay
Jack Lucknow, a self-taught archaeologist, reviewed that he found absolutely fuck all.
Jack has therefore concluded that 250 years ago, Canada had already gone wireless."

Just makes you bloody proud to be Canadian, doesn't it!
