We found the detour to the public parking lot at the Lock and dam in La Crosse, Wisconsin, and didn't have to wait too long to see a small barge coming into the lock.
It was sand for the construction site a little farther north of the lock. The interstate 90 bridge is being redone (which connects Wisconsin to Minnesota) and it's a big project.
This poor houseboat was just resting against the shore between the lock and the I-90 bridge. I wondered how it got there.
