We revisit a story about two men playing in the ice sheets of Lake Michigan in Hyde Park on their daily swim. Elizabeth Brackett reports. Read an article about the risks of swimming in cold water.

Back in 2012, we met two men – Greg Lane and Andre DeMar – who regularly swam in Lake Michigan, including during frigid Chicago winters. We spoke with Andre DeMar today to find out if he still swims in the frigid waters. It turns out he does. In fact, he swam in Lake Michigan this morning as the outside temperatures hovered around -2 degrees – without windchill. Read an interview.
