brettjrob Posted June 18, 2014 Share Posted June 18, 2014 At the end of the long and seemingly endless road of miserable patterns, spectacular last-minute busts, and everything in between, it turns out 2014 in the Plains wasn't unimpressive. It just all came down to a 36-hour, 200-mile spatiotemporal window. Unreal. Link to comment Share on other sites More sharing options...
