I thought of that [Theory of Relativity] while riding my bicycle.
Bicycles are almost as good as guitars for meeting girls.
—Bob Weir, Grateful Dead
The cyclist creates everything from almost nothing, becoming the most energy-efficient of all... animals and machines and, as such, has a [genuine] ability to challenge the entire value system of a society.... The bicycle may be too cheap, too available, too healthy, too independent and too equitable for its own good. In an age of excess, it is minimal and has the subversive potential to make people happy in an economy fuelled by consumer discontent.
[A] key factor in the development and planning of most trails is local, grassroots efforts: that is, the citizens who drive the local, state, and federal government to act. Everything from establishing the vision and need for greenways to defining specific trail corridors, to participating in the zoning process, to forming citizen coalitions, to developing guidelines for trail use and access should be within the abilities of each citizen. With broad-based support, the vision of a national system of trails can be realized.
— American Trails, Trails for All Americans report, 1990
Americans are seeking trail opportunities as never before. No longer are trails only for the ‘rugged individualists’ pursuing a solitary trek through breathtaking wilderness … users include young people and senior citizens, families, individuals and organized groups, people with disabilities and the physically fit.
—American Trails, Trails for All Americans report, 1990
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.
—Stewart Lee Udall, Secretary of the Interior
