Pittsburgh Steps

The author, Bob Regan, a geophysicist affiliated with the University of Pittsburgh. Using Geographic Information Systems technology and riding a bicycle up and down Pittsburgh's many hills, he meticulously located and plotted every set of steps in the city over a period of several years. He counted the number, made notes about type, usage, and unique features, and, most happily for us, talked to everyone he encountered along the way from residents to bike police.
