So many bikes litter the lake that the Fire Department, the rideshare company and a group of volunteers dubbed the Divvy Fishers Society can barely keep up.
Are the bikes just left parked around the city? Here in Montréal, we have Bixi, with docks for the bikes every few blocks, and bikes have to be returned to a dock when you're done (or you'll get docked for the price of the bike, pun intended) so we don't hear about discarded bikes much.
