Mississippi River Lock and Dam

at Dubuque, Iowa. You can see a triple-wide barge that has just gone through (heading north) in the bottom left. Taken at dusk from a park on the bluff. The hills on the far side are Illinois.

Amazing

That's got to be some feat on the part of the tug pilot - not much clearance on either side of that lock!

Wow, Can't believe that barge can even get through there. Cool capture.
