(link) The Harley-Davidson is more than a two-wheeled miscreant-hauler; it's one of America's most important indigenous technologies. The 45-degree V-twin engine has remained remarkably unchanged since it was introduced in 1909. Now the Harley has its own museum, which opened on July 12 in Milwaukee, the bike's birthplace. Inside the steel-framed compound, you'll find plenty of antique bikes and memorabilia, including the original outlaw: Serial Number One. There's also a "family tree" that shows how engineers modernized the distinctive two-cylinder engine without sacrificing its signature raw rumble.
But confining all that heavy metal thunder indoors would be sacrilege. So Pentagram, the chief design firm on the project, turned 20 acres of industrial land into hog heaven: The three buildings containing galleries, archives, and the obligatory store are arranged around an intersection of 60-foot-wide roads — broad enough for four rows of parking and two traffic lanes, just like at Sturgis — creating an ever-changing exhibit of visitors' bikes. "It's important to have a real museum," Pentagram architect James Biber says, "but also to have a kind of museum on the street." There's car parking as well, but the lots are a bit of a hike from the entrance; this is one stretch of pavement where motorcycles always have the right of way.
