BobbyG and everyone else: In some areas, the bike routes that google maps provides are quite good, and that includes NYC and environs. I'd be surprised if it isn't also true in Chicago. Not only that, when I ask for a bike route, I can specify my own bike or Citi Bike, because the routes will be slightly different. I just did a test and asked how to get from my home to a place about 3 miles away. The Citi Bike route tells me where to pick up a bike and where to drop it off. I wonder if it is using the available real time data on how many bikes are available at the first station and how many open docks are available at the second one. Chances are that it does. Interestingly, the route for my own bike runs along the river path while the Citi Bike route runs through the streets. It's shorter that way, but I can only guess the reason it has that difference. Anyway, even if you're pressed for time and don't know the streets, putting trust in google maps isn't the worst idea. I don't know about Divvy, but checking a bike out for the first time with Citi Bike can be a stumbling block. I've seen a visitor from a foreign country fail and give up because payment systems and texting are still not transparent enough.
