This gallery is a look at several of the most prominent and mysterious 'Shadow Organizations' that operate in the Upper-Midwest states of Iowa, Minnesota, and South Dakota. Over the decades, their Midwest footprint grew steadily, establishing a lasting presence across Iowa, South Dakota, and Minnesota. The U.S. Department of Justice classifies them as an Outlaw Motorcycle Gang (OMG). If you’ve ever looked up at the brick facade of an old main-street building in Iowa, Minnesota, or South Dakota, there's a decent chance you've seen three interlocking chain links stamped with the letters FLT. These days, the group operates in every state (including lodges in Iowa, Minnesota & South Dakota), and several countries around the world.
