We are camped in Iowa ( north of Omaha, NE ) near the DeSoto National Wildlife Refuge. After visiting the sunken Steamboat Bertrand display, we took the lovely trail to the site where the craft was excavated. Such an interesting story! We stopped along the way to smell the flowers and watch a hundred or more Swifts building nests under the eaves of the visitor center. One day, we should return for the Spring or Fall bird migration. I imagine that’s an awesome sight.
