Baltimore has set in motion plans to install 250 bikes (in 30 stations) around the city next summer.
This is definitely a positive "green" step along with the push for additional marked bike lanes, Zip Cars, the Charm City Circulator, and charging stations in city garages. Let's hope the trend continues! The base price for membership will probably be in the $60 a year price range, though discounts do exist for students, seniors, etc. You can also buy a 24 hour and multi-day memebership, which will be very useful for tourists visiting Baltimore.
