The Chicago Cubs traditionally have not minded their neighbors watching games free from their rooftops adjacent to Wrigley Field, but they do object to a private club charging for rooftop parties.

Club President Donald Grenesko says he has asked the Cubs’ architect to design a barrier to be erected behind an outfield bleacher section that will block the view of the Lakeview Baseball Club, organized by ERTA Development, which owns the building.

“It’s not the money,” Grenesko said. “It’s the principle. They’re stealing our product, and that just grates on us.”
