CHICAGO -- Two local businessmen have a new idea to bring more tourists to Chicago.
They want to put them in these high-wire gondolas.
The zip line would take riders down the Chicago River to Navy Pier.
They say this tourist attraction could bring the city an additional 330-million dollars a year, but they also say it would not cost the city anything because they expect investors would line up to finance it.
They estimate it would take 18 months to build, once all the logistics are figure out.
