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.

Captains Getaway in Arnolds Park is the spot for the best live music entertainment in Okoboji. Highlighting the talent rolling through the lakes is the Nashlo Series of talented up and coming performers along with artists we have all heard of. Captains Getaway in Arnolds Park is the spot to be in Okoboji for the best live music!

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.
