Dam removal is no longer the work of a fictional Monkey Wrench Gang. It's real, upon us, and a cornerstone of the modern environmental and cultural movements. Starting in the summer of 2011, filmmakers Ben Knight, Travis Rummel and Matt Stoecker began a series of road trips across, up and down the United States. They accessed remote rivers by air and floated some of our country's critical waterways to research and chronicle a growing movement to tear down obsolete dams. Over the next two-plus years, the crew traveled from Maine to California and Alaska to Arizona to document some of the concerns about America's 80,000 dams and the reasons behind the increasing number being removed annually. The result is the film DamNation: 80,000 dams, 51 interviews, one film – and now one hat to commemorate the filmmakers' efforts. The DamNation™ Trucker Hat is made of 100% organic cotton canvas and polyester mesh.
