Plot: John McGivern heads north on I-43 to explore Sheboygan. Did you know that you can surf, go the theater, shop the oldest hardware store in Wisconsin, learn about Hmong culture, the history of Sheboygan and eat the most delicious hard rolls in the state all with about three miles? John Gurda starts off on the lakefront, and it's a short trip to great destinations like the Kohler Art Center, the Blue Harbor and Bookworm Gardens
