Without question, bicycling is an efficient, economical and environmentally sound form of transportation and recreation. Bicycling is a great activity for families, recreational riders and commuters. Hillary, Chelsea and I have bicycles….

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. 

—President Reagan’s Commission on American Outdoors, Americans and the Outdoors, 1986
