fun facts about the burgh

So in my effort to learn as much as I could about Pittsburgh over the weekend, I stumbled upon the following facts: Hmm...

--the word "downtown" is actually pronounced "dahntahn" as if it rhymes with "wonton"

--Pitt's "Cathedral of Learning" is the tallest academic building in the Western Hemisphere

--the pull tab on aluminum cans was invented here in 1962

--so was the Big Mac

--and the Polio vaccine

--Pittsburgh has more bridges than any other city in the world (it has 2,000... Venice, Italy only has 409)
