Something that caught my attention this week is Bicycle City - a planned car-free community where people live, work and visit. Its eco-friendly design is healthy, sustainable and could be applied to urban or non-urban areas. Residents who own a car can conveniently park it on the edge of the community nearest their home.
The first Bicycle City is planned near Columbia, South Carolina, but there are many possible locations both in the US and elsewhere (including here in the UK). Check it out.
