Sheep and the City: Nashville's Urban Shepherd

Zach Richardson's landscaping company isn't your average group of grass cutters. His team, the Nashville Chew Crew, is made up of 60 sheep and his border collie, Duggie. Richardson takes his group around Nashville, Tennessee, to help control invasive species and overgrown areas around town. Call it green landscaping or smart pest control. Just don't call it sheepish.
