This 20-acre campus is a must-see for riders and a worth-the-trip spot for the curious (left). It tells the story of a scrappy Milwaukee company that began in 1903 as a motorcycle innovator and has evolved into a brand that embodies the feeling of wind in your hair. Hands-on exhibits let gearheads tinker with old engines, a "Rebels and Outlaws" display shows how riders gained that rep, and a movie room lets you board one of 10 Harleys and "ride" along Midwest farms and rivers. h-dmuseum.com 
Motorcycle fans also can take a free one-hour tour of the famed Harley-Davidson Factory in nearby Wauwatosa; you'll see powertrains being assembled and tested. Tour information
