It's hard to miss the advertisement: A huge banner plastered across a city bus, urging anyone injured by a chiropractor to call for help.
The ad is so big, in fact, that it's drawn the attention of the World Chiropractic Alliance, its California law firm and chiropractors across the nation.
The WCA is threatening to sue the Greater Bridgeport Transit Authority if the advertisement is not removed. The group is also demanding that the Waterbury transit district pull an identical ad on a bus in that city.
