I've been using Penn Pilot for a long time now. Combining Penn State's work with Penn PIlot with the University of Pittsburgh's maps and photo archives of their city, one can get a lot of help with a track plan. Sheets 25 and 26 of the City of Pittsburgh Geodetic and Topographic survey and APS7278 from the USDA photo surveys have given me everything I need to know.
