Welcome to “Tell Me Something,” a weekly feature that invites local scholars to share a single interesting, insightful, or cool thing they’ve learned in their careers that most people don’t know, which can help us better understand our world or give us new perspectives on common issues.
This week, epidemiologist Kristen Rappazzo joins Aaron to share details about an old practice whose effects still linger today: burying old junk cars along rivers to shore up their banks. (There are examples of this in western North Carolina, including along the French Broad River.)
