I thought of that [Theory of Relativity] while riding my bicycle.    

—Albert Einstein

When man invented the bicycle, he reached the peak of his attainments. Here was a machine of precision and balance for the convenience of man. And (unlike subsequent inventions for man's convenience) the more he used it, the fitter his body became. Here, for once, was a product of man's brain that was entirely beneficial to those who used it, and of no harm or irritation to others. Progress should have stopped when man invented the bicycle.

Next to a leisurely walk, I enjoy a spin on my tandem bicycle. It is splendid to feel the wind blowing in my face and the springy motion of my iron steed. The rapid rush through the air gives me a delicious sense of strength and buoyancy, and the exercise makes my pulse dance and my heart sing.

—Helen Keller

The world lies right beyond the handlebars of any bicycle.

The proposed Ohio River Trail, when completed will enhance and further develop recreational opportunities for the communities along the Ohio River Trail corridors as well as the region, by linking existing and proposed pedestrian, bicycle, recreation, open space, and transportation facilities while protecting environmental and cultural resources and improving public access to the river’s edge. One of the major outcomes of the project will be to foster further recreation and cultural-based economic development within the local communities and the region, capitalizing on the synergy of ecotourism and the potential development of a larger recreation and parks system as a way to reposition all the evolved communities for the 21st century business and lifestyle needs.

Blue Trails are an organizing tool that galvanizes citizen support for clean water and healthy riverside lands. They inspire people to protect important habitat and provide corridors for people and wildlife.  While specific protections vary from community to community, Blue Trails are often associated with conservation easements, land acquisition, stream buffer requirements, stream flow protections, and higher water quality standards.
