MARSHALL, MI (WTVB) - The History Channel debuted its new reality show last night. “Dark Horse Nation” follows the lives of a bunch of free spirits with full beards who like to fire guns and work in a unique industry of their own choosing. If that sounds like “Duck Dynasty” to you, it’s probably not a mistake. In this case they all work in a craft brewery in Marshall, Michigan, which makes it a little more interesting. One other difference, no southern accents. They held a big screening party at the Dark Horse Brewery in Marshall last night.
