In December 2019, Curious City held an event at the Hideout that was all about Chicago’s most ubiquitous vermin: rats.

The event was inspired by a question Curious City received from then-12-year-old Justin Carrasco, a Cicero resident who wanted to know just how many rats call Chicago home.

To answer Justin’s question, the Curious City team took a trip to Lincoln Park to visit what’s been called “Chicago’s most rat-infested alley.”

We also heard from a number of listeners who shared some of their most traumatic rat encounters.
