Founded in 1960, the Three Sons has been a staple of Milford, IA retail. From Herman and Emil Richter, owners, was born the University of Okoboji, a ficticious university that calls the entire Iowa Great Lakes the campus of the U of O. Part of the experience of shopping the three sons, if walking the old battered floors, and taking a trip upstairs for half price, plus a buck. Brands you would expect in Milford Iowa are abundant, such as Patagonia, Oakley, Under Armour, Tommy Bahama, and more. There are currently 2 other stores; one at the amusement park, and another near the Regal Beagle called the bridge store. No self-respecting visitor to Okoboji leaves without visiting one of their stores.

Okoboji Boat Works is home to "The Fish Shack" and "The Inconvenience Store". Formerly a marina of thriving boat sales since 1890, OBW now offers up many different rentals, a 24 hour gas dock, excursion boats, and more. I remember the days as a child of fishing for crappie and blue gill here and along the docks of Smith's Bay. Though the scenery has changed, the outstanding fishing has not.
