Wife and I took our grandchildren to the National Mississippi River Museum at Dubuque Iowa over the weekend.
It is a museum that tells the story of the Mississippi River from the earliest man to today.
The museum is on a site that built and repaired riverboats which mainly were/are paddle boats. On site is the dredge paddler William M Black which is a bed and breakfast place.
There are on premise several steam engines used by paddle boats which two I enclose.

Nice photos, need more like them
Must have been a great trip
cheers
