Tom Dempsey, vice president and general manager of the Sears Tower, used to grab a taxi when he was running late for a meeting in another part of the Loop.
Now he gets on a bike -- one of three "courtesy bikes" the nation's tallest building has offered tenants since the start of the month.
"It's very easy, and it's often quicker," said Dempsey, who's not afraid to bike in a suit. "We find it to be a great convenience to our tenants."
