I came to buy a few copies after seeing this in Bicycle Times but I'm afraid the Pittsburgh map has some major errors. It's got the SouthSideTrail at the Convention Center (it's not). It's got the Great Allegheny Passage northwest of OTB - but the GAP crosses the Mon at the Hot Metal Bridge (iow, the GAP marker is on the wrong side of the river). I believe the NorthShoreTrail marker is in the wrong place - the NorthShore is more along the PNC Park segment, the place where the NorthShore Marker is drawn is the Chateau Trail. Great concept, nice pictures, but the details are wrong. Vannevar Bush vbush90@gmail.com
