The first sign appears a few miles away, stuck into the frozen grass alongside I-43. "Motorcycle Liquidation" it reads, black letters on a yellow background, with an arrow pointing right. I exit at East Troy and head north toward Buell Drive, and the soon-to-be-vacant Buell Motorcycle factory. It's a sunny, bitter-cold January morning in Wisconsin, barely above zero. Yet despite the frigid temperature, more than 500 people are lined up outside, waiting for the Buell Motorcycle Factory Liquidation Sale to open.
