Four-wheel-drive technology was developed here early in the twentieth century, and in the 1920s Walter Olen and the company's heavy-duty trucks traveled far and wide. They helped build railways in China, a project that led to Olen's hauling home a hefty souvenir, a portion of the Great Wall of China, which, to date, has protected Clintonville from possible invaders from the North. A gift from revered statesman Sun Yatsen, it is believed to be the only section of the Great Wall ever to leave China.
Eventually Olen's 1,700-year-old Chinese bricks were joined by stones from such places as Jerusalem, the Petrified Forest, Yellowstone National Park, and the Dakota Badlands, along with a Wisconsin millstone. The exotic mementos are lined up in Pioneer Park on the banks of the Pigeon River near two historic houses and the Four Wheel Drive Museum, which displays original four-wheel-drive vehicles -- a must visit for SUV or urban assualt vehicles seeking to return to their roots. The museum is open from 1:00 to 4:00 each weekend from Memorial Day to Labor Day.
