Before WWII, street trolleys were once a ubiquitous feature in all medium-to-large cities in America. You can still see the tracks embedded in streets from Philadelphia to Fresno.

We talk with Barbara Perry Bauer from TAG Historical Research and Consulting about this unique glimpse into the region's past.
