Arts and culture
Annual cultural events
Danube Fun Days, the city's annual celebration, is an extended weekend with lots of traditional events taking place during the second weekend in July. The Wednesday night ice cream social at the United Methodist Church kicks off the celebration and always draws a good turnout. For the athletes, Fun Days hosts one of the area's best volleyball tournaments and a softball tournament. The parade typically draws 50+ floats and is a favorite for the locals. There is also a flea market in the park and a treasure hunt in which a medallion is hidden and the finder gets a prize. The street dance brings live music to town and ropes off a beer garden with burgers and hot dogs. After the band calls it a night, the younger adults typically find themselves at one of the many late-night house parties hosted throughout town. Fun Days serves as a homecoming of sorts for many of the city's former residents and a great chance to catch up with some long-lived camaraderie.
