For centuries, maps have shown us how to get from point A to point B. But they’re much more than that. They’re a record of what people care about. How do you preserve these stories when maps are no longer on paper? In this Backstory piece, Larry Potash introduces us to a Chicago family who have been in the map business for 5 generations. Backstory with Larry Potash airs Sunday nights at 6:30 p.m. and 11 p.m. on WGN, or stream it anytime on the WGN+ app on your smart TV with Amazon Fire, Roku, and Apple TV. Check out the Backstory podcast at WGNtv.com/Backstory via Apple Podcasts, Google Play, or wherever you get your podcasts.
