I thought of that [Theory of Relativity] while riding my bicycle.
Ever bike? Now that's something that makes life worth living!...Oh, to just grip your handlebars and lay down to it, and go ripping and tearing through streets and road, over railroad tracks and bridges, threading crowds, avoiding collisions, at twenty miles or more an hour, and wondering all the time when you're going to smash up. Well, now, that's something! And then go home again after three hours of it...and then to think that tomorrow I can do it all over again!

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.

The establishment of a nationwide system of trails will be an accomplishment worthy of a place beside other major conservation programs... The fundamental objective of a nationwide system of trails is to provide simple, inexpensive recreation opportunities for all people by having an abundance of trails for walking, cycling, and horseback riding near home, as well as providing some major historic and scenic interstate trails of national significance.
