The V-Twin engine is impressive. The endless chrome and countless bike modifications are amazing.

When it comes to engineering wonders, though, the "World's Largest Beer Bong," takes the case.

This huge hose contraption, operating this weekend at the huge parking lot shared by Milwaukee Harley-Davidson and Silk Exotic near Highway 100 and Silver Spring Road, has become a tourist attraction.

I can just sense that students at Madison, Marquette and every other college are trying to top it.

This thing just might make my friend Andy Tarnoff appreciate the festivities of Harley's 105th.
