Every day, Baltimore Sun employees cross a sturdy suspended walkway between the newspaper and its parking garage. Called the skywalk, it hovers 200 feet over Centre Street. It was built in 1978 of bulletproof glass, concrete and steel, and is one-quarter of a mile long.

I’m just kidding. I don’t actually know any statistics about the skywalk at all. I thought if I started asking questions like that, a couple of FBI guys would come to my door to see whether I’d figured out how much plastique I needed. I am not a disgruntled former employee, though.
