Make your way out of Chicago today and head for Milwaukee, Wisconsin. This former brewing powerhouse now boasts plenty of cultural and historic sites along with abundant beer halls and taverns. The Milwaukee Art Museum is worth visiting, not only for its impressive collection of 30,000 artworks but also for its distinctive Modernist architecture. For petrol heads, the Harley-Davidson Museum is also a must-see. From Milwaukee, continue into Door County, a peninsula known as ‘Cape Cod of the Midwest’ thanks to 30 miles of coastline and ten lighthouses. Stay 2 nights at the Eagle Harbor Inn, Ephraim (or similar).
