The restaurant 14 years ago trademarked the right to put goats on a roof to attract customers to a business.... So when a tourist spot 750 miles away decided to deploy a rooftop-caprine population, Mr. Johnson made a federal case of it. Last year, he discovered that Tiger Mountain Market in Rabun County, Ga., had been grazing goats on its grass roof since 2007. Putting goats on the roof wasn't illegal. The violation, Al Johnson's alleged in a lawsuit in the U.S. District Court for the Northern District of Georgia, was that Tiger Mountain used the animals to woo business."
