"One of the best things about the Harley-Davidson Museum, 400 W. Canal St. in the Menomonee Valley, is that visitors get to see just about everything.
The expansive galleries – which opened a decade ago now – are packed with bikes, what the museum calls "costumes," memorabilia, historical documents, photographs, curiosities and more.
Guests can even head across the skywalk for a peek into the archives and the restoration and conservation shop through a metal grate.
Plus, the museum, built on marshy land along the Menomonee River, doesn't have a basement. This makes the idea of "spelunking" a little challenging ... or does it?"
