The Chicago Architecture Foundation conducts boat tours up and down the Chicago River, giving a unique perspective on our city's buildings.

From yesterday's CHICAGO TRIBUNE:


Witnesses said they had just begun the Chicago Architecture Foundation's 1 p.m. tour when they passed under the bridge and a cascade of a "brownish-yellow" substance rained on them. About two-thirds of the passengers seated on the upper deck of Chicago's Little Lady were soaked.

Passengers said they looked up to see at least one, possibly two charter buses rumbling above.
A volunteer tour guide at the boat's helm reassured passengers that they had been splashed with water. But the foul smell prompted suspicion.

There was "stunned silence initially. Then sort of this horrible realization as they began to smell themselves as to what happened," said Steedman Bass, 35, of Boston, who was a passenger on the boat but was not sprayed. "It was horrific."

Fortunately, one of the passengers was able to get the license plate of the bus. Turns out the bus belongs to The Dave Matthews Band.
