Really unbelievable!!! Did the force of the current flip the tug boat under the bridge and it popped up on the other side? I'm trying to envision what went on under the bridge. Oh forget it....it just pushed the boat upright under the bridge it appears from studying the photos further. Still pretty amazing. Must have been an amazing ride.
The captions really tell the story-- "Uh Oh, the Boat is Sideways!" Done by Miguel of Fat Chicks In Party Hats, no doubt.
