Curious City - No cars, no road salt: How one Midwestern community avoids salt all winter

Chicago — like so many other frigid American cities — can’t seem to kick its dependence on road salt. In our last episode, we learned how winter weather on both ends of the thermometer can impact the local economy. Some businesses come out on top during the coldest winters: auto mechanics repairing cars when they hit a pothole, snow plow companies shoveling out small businesses and rock salt providers when the roads get icy. But chloride from salt is harmful to both our natural and built environments. You’d be hard-pressed to find a cold-weather community that avoids road salt altogether, but we found one! In this encore presentation, we visit a place way up north, Mackinac Island, Michigan. Dominick Miller, chief of marketing at the Mackinac State Historic Parks, tells us about how the island deals with snow and ice in the winter without laying down a single grain of salt. And it has a lot to do with the fact that cars have been banned on Mackinac Island for over a century.

Curious City - What was it like for women working in Hoover’s FBI?

For decades, the FBI was a man’s world. Anybody else was just living in it, especially the administrative staff. In the last episode, we learned how the bureau recruited high school girls for clerical work during the 1940s. But for decades women were explicitly prohibited from becoming special agents. Western Springs resident Jane McCarty was hired out of high school in the late 1960s to work as a stenographer for the FBI. She held several positions during her more than four decades at the organization. Today, the former president of the Society of FBI Alumni talks about the ebbs and flows of women’s access to leadership and autonomy within the bureau. She endured a sexist work environment but later witnessed the first women become FBI special agents.

Curious City - How Ella Jenkins’ Chicago childhood shaped her iconic children’s music

From school assemblies to “Mr. Rogers Neighborhood,” Ella Jenkins was a rhythm specialist and children’s music pioneer. Her childhood in Chicago was her launching pad. In our last episode, we learned that the first Chicago public school named after a Black person was DuSable High School, in honor of Chicago’s first nonindigenous settler, Jean Baptiste Point DuSable. It turns out some of the most notable Chicagoans graduated from DuSable, including Mayor Harold Washington, historian Timuel Black and Jenkins. Today, we bring you a conversation about this music icon, who harnessed curiosity, life experience and charisma to create some of the most unique and prolific art of the 20th century. Jenkins forged a path in the music industry during a time when children’s musicians didn’t really exist. She persevered through the civil rights era, took ownership of her music in an industry that often took advantage of women and made the focus about children. Professor of American studies at George Washington University Gayle Wald sat down with Curious City Editor Susie An at the 2025 Evanston Folk Festival to talk about Jenkins’ life. Wald is the author of “This is Rhythm: Ella Jenkins, Children’s Music and the Long Civil Rights Movement.”

Curious City - Why did Chicago widen Ashland Avenue?

If you pay attention to street signs in Chicago, you’ll notice imperfections and many quirks. Paul Durica of the Chicago History Museum said a coworker informed him that North Avenue becomes North Boulevard when you’re east of Clark Street. “And I was like, what?” Durica recalled. “And it does! And it's because here we are, now in the park.” One of Chicago’s major arteries, Ashland Avenue, has a rich history of its own. In our last episode, we looked at why streets like Ashland are occasionally labelled boulevards (like North Boulevard, sometimes the answer is because the street is adjacent to a park). Today, we’re looking closer at the history of Ashland Avenue, including how it became a major thoroughfare and why the city widened it at great expense 100 years ago. (The short answer? To accommodate car traffic.) Contributing are Durica and Northwestern Professor Bill Savage, author of a forthcoming book on the anomalies and politics behind Chicago’s grid system.

Curious City - We can’t name ‘em all, but here are some of Chicago’s greatest films

From high-speed chases to preposterous parades, Chicago dazzles on the silver screen. Last episode, we attempted to uncover the best movie ever filmed in Chicago. What we found was that it was impossible to name a definitive best, let alone name every movie that deserves recognition. Today, we dive deeper into movies that resonate with Chicagoans with two film critics: Marya E. Gates, author of Cinema Her Way: Visionary Female Directors in Their Own Words and Robert Daniels, associate editor of RogerEbert.com. They argue that the city doesn’t just look good on screen, it also helps tell stories that are reflective of its residents. Gates and Daniels talk about Chicago movies that highlight crime and political tropes (like “The Untouchables,” “Medium Cool,” and “Call Northside 777”), movies that bend space and time to navigate through Chicago’s geography (like “The Fugitive” and “Blues Brothers”), and movies that follow teenagers as they romp around the city (like “Cooley High” and “Ferris Bueller’s Day Off”). Plus, they’ve got recommendations for Chicago movies that may have flown under your radar.
