It was wacky activity on water Saturday at the EQT Three Rivers Regatta, as it held its annual “Anything That Floats” race. From the simple — an air mattress lashed with pool noodle — to the more elaborate — a bicycle-powered mock-up of the Roberto Clemente Bridge, spectators lined up along the Allegheny River Downtown came prepared to root and laugh.

Brianne Cassidy and Stephanie Georg, the crew of the water-worthy mattress, were among the teams crossing the finish line in one piece. Cassidy was quick to give credit where credit was due — tape. “It pulled the whole thing together,” Cassidy said, as the two sipped celebratory beers.
