This week, a major rainstorm left several New York City subway stations flooded with water. The 28th Street stop on the 1 line in Manhattan got it especially rough. Videos on social media show water shooting up out of a manhole on the station's platform like a geyser. It's not the first time this has happened, and the city's precolonial topography is at least part of the reason why. WNYC's Ramsey Khalifeh joins Weekend Edition host David Furst to talk about why this station is so prone to severe flooding.
