I thought of that [Theory of Relativity] while riding my bicycle.
Whenever I see an adult on a bicycle, I have hope for the human race.
Bicycles are almost as good as guitars for meeting girls.
—Bob Weir, Grateful Dead
If I can bicycle, I bicycle.
Bicycle facility planning is commonly thought of as the effort undertaken to develop a separate bikeway system composed completely of bicycle paths and lanes all interconnected and spaced closely enough to satisfy all the travel needs of bicyclists. In fact, such systems can be unnecessarily expensive and do not provide for the vast majority of bicycle travel. Existing highways, often with relatively inexpensive improvements, must serve as the base system to provide for the travel needs of bicyclists. Bicycle paths and lanes can augment this existing system in scenic corridors or places where access is limited. Thus, bicycle transportation planning is more than planning for bikeways and is an effort that should consider many alternatives to provide for safe and efficient bicycle travel.

Greenways can draw people together in their communities to provide open spaces for all close to their own homes. They have the potential to be this country's most important land-based effort for conservation and recreation in the next several decades. They can draw private and local entities into lead roles in provision of recreation opportunities. They can capitalize on the entrepreneurial spirit of Americans and give pride of accomplishment and responsibility to millions of people in every community. They can protect vital water, fish, wildlife, and recreation resources as integral parts of the growth of cities and communities. And, if greenways truly capture the imagination and boldness of the American spirit, they could eventually form the corridors that connect open spaces, parks, forests, and deserts— and Americans— from sea to shining sea.
