CHICAGO (AP) — The Chicago Cubs and owners of rooftop venues across the street from Wrigley Field appeared to be headed toward the legal equivalent of bench-clearing brawl, after the team announced Thursday it will now push to erect more signs in the outfield than the city has approved.

Owners of the 15 rooftop venues immediately vowed to fight in court what they see as a threat to their views and livelihoods.
