At the outset of a Chicago River boat tour Sunday, Capt. Sonja Lund deadpanned that passengers should not look up with their mouths open when passing under the city’s grated bridges, lest they get a true “taste of Chicago.”
About 15 minutes later, passengers got more than that. They got a deluge when the boat was doused with a foul "liquid substance" that appeared to drop from one or two charter buses as the boat passed under the Kinzie Street bridge, passengers and tour officials said.
