Peterborough lift locks

Peterborough, Ontario, Canada

"On the boys' first bike ride ever along the Trent Canal, we arrived at the lift locks
which, at 65 feet, are the tallest hydraulic lift locks in the world. The whole thing is
operated by the weight of water only. It's an amazing engineering feat!" --Einar
