We stopped to see the Bonneville Dam along the Columbia River. We happened to time it just before a tugboat arrived pushing three huge barges strapped together.
Picture 1: The lower locks open so that the barges can continue their route down the Columbia toward the coast.
Picture 2: The barges and tug are designed so that the combination of tug and barges just fits within the lock, with literally inches to spare!
Picture 3: Old cars on their final trip.
