Cud v. Kudzu

Our city's hired goats to take out invasive kudzu. Cheaper & better than people:
At $375 a day, the cost to rent a herd of goats is comparable to hiring a contractor. But employing farm animals avoids compacting the soil with heavy equipment or polluting the nearby northwest branch of the Anacostia with an herbicide.
Better yet, goats work day and night, rain or shine. They get the job done and they don't talk baaaaack -- for the most part.
I wonder: would they clear out the brush in my back yard?
