To mark the beginning of Lent on the Christian calendar, Polish-Americans celebrate Paczki Day or Fat Tuesday. It's a celebration before they fast for 40 days. At least that's the history behind it. But there's more to it than that — especially here in Metro Detroit, a place with a booming Polish population. WWJ's Zach Clark sat down with Renee Applegate from Michigan State University to talk about her own experiences with Paczki Day and a paper she wrote on the history of Paczki Day. Mark Lackowski, a Detroit native and Polish musician, also joins Zach to share what the day means to him.
