Evan Osnos tackles Chicago's role in a divided America at city festival

Why Chicago: "Frederick Jackson Turner had it right in 1901 when he described Chicago as the place where 'all the forces of the nation intersect,'" Osnos tells Axios.

• As Osnos tells stories about how events in each place have divided us, he also shows how they converge.
• Case in point: He explores how subprime loan architects on the East Coast affected the livelihood of families in Chicago neighborhoods like Auburn, Gresham and Parkway Gardens.

What will surprise Chicagoans: Our assumption that all our guns come from Indiana and Wisconsin is wrong.

• A 2016 federal analysis showed that more guns come out of "West Virginia to be used in crimes than from any other state," Osnos says. "West Virginia's guns were showing up in places such as Philadelphia, Albany, and Chicago at a rate more than twice the national average."

The inevitable food question: What does he eat in Chicago?

• "My cells are 70% water and 30% carne asada tacos from La Pasadita."

• The festival runs through the fall.
