So I'm interning for this really neat organization called Bicycle City this summer. Bicycle City is a planned car-free communities project. Its vision is a future with sustainable cities and communities that are eco-, people- and animal-friendly.
They are interested in promoting bicycle- and walkable-friendly cities anywhere in the world, and they have an office located here in Pittsburgh:

Check out the website and let me know if anyone would like to join the newsletter. The more support they get, the more successful their project will be.
