Meet the Chew Crew: urban sheepherding takes the spotlight

Along the Cumberland River just north of downtown Nashville, in the US state of Tennessee, tourists on party boats float past the recognisable skyline.

But they can also see something a little less expected: hundreds of sheep nibbling on the grass along the riverbank. It follows a new trend in urban landscaping: using an old method to cut grass and do other upkeep.

Zach Richardson is the urban sheepherder who manages this flock. He said tourist boats go out of their way to let their passengers get a closer glimpse of the Nashville Chew Crew. They can be seen grazing a few hundred yards away from densely populated buildings.
