	Banquet Hall in the Dry Run Sewer, Waterloo, Iowa. In 1904, Waterloo, tired of cleaning up after floods, decided to enclose Dry Run Creek in a large storm sewer. To celebrate its completion, the Iowa League of Municipalities then held its annual banquet within the sewer. Guests entered at points between Randolph and Wellington and found a sumptuous feast laid for 400. Source: Original postcard circa 1915. Collection of Jon C.
