Brochures, maps, videos, guide books, and cassettes would be produced for distribution at the participating sites. A number of implications stem from the establishment of a national historic trail. Grassroots initiatives and continued interest and support are crucial. Problems could arise because federal incentives and support would go to historic businesses but not to newer enterprises. This could confuse visitors.
Federal legislation is needed to authorize a national historic trail.
Before legislation can be enacted, a recommendation for a trail must pass the National Park Service System Advisory Board. There are also a number of implications specific to Route 66 as a national historic trail. A prime consideration is the traditional focus of such trail. Currently, all national historic trails do not allow motorized vehicles. They have ceased to evolve, and Route 66 does not easily fit into the NHT mold.
