Fifty years ago, when Congress investigated rock ’n' roll as a scourge on the young, who would have thought there would eventually be a Rock ’n' Roll Hall of Fame Museum? There's a Woodstock museum, too. And now, Harley-Davidson, another symbol of rebellion, gets its own museum. If you're headin' down the highway, lookin' for adventure, rumble on in to downtown Milwaukee (the city made famous by Pabst Blue Ribbon) and check out the Harley-Davidson Museum, brilliantly designed by James Biber with interactive exhibitions (below) designed by J. Abbott Miller of Pentagram/New York.
