A heard of sheep have taken on a new role of landscapers at Fort Negley.
They're called the "chew crew," and they use their teeth to do a the yard work. The sheep eat their way through overgrown brush around the historic site near downtown Nashville.
The four-legged lawn mowers are not only cost effective, but they can also clear the historic site without damaging it, and they don't go anywhere without some canine muscle.
