Divvy has put up a station suggestion map. Letting Divvy know where users would like to see more stations is great to make sure that important gaps are closed.
I personally would love to see more L and metra stations have a Divvy station nearby. This lets people connect between public transit and their destinations without making often awkward bus transfers. Its one of my main Divvy uses, since I dislike bringing my bike on board, or locking up at stations since most have high theft rates.
There was a map like this put up before the initial docking station rollout. I wonder if the suggestions are all new or are leftover from last time.
