Back int eh mid 90's, the college I was going a 6in diameter (or so I was told) fiber optic line ran all the way up from Syracuse to Potsdam, NY. Apparently it cost like 10k per mile at the time.
Well some jackass didn't "call before you dig", and snapped the fiber line in half with a backhoe. They sent him the bill. And we had no Internets (apparently google spell check thinks this should be capitalized!) for 2 whole weeks!
