Great stuff. I’m curious as to who writes the material for these markers and what organization is responsible for vetting the material and installing them?

2. RE: Who/what organization is responsible for the content of these markers?
The National Scenic Byways Program appears to be responsible for these signs, which are produced in cooperation with state and local historical societies. They have a page for the press here: www.byways.org/press/ and this is a quote from their website at www.byways.org.
“The National Scenic Byways Program is part of the U.S. Department of Transportation, Federal Highway Administration. The program is a grass-roots collaborative effort established to help recognize, preserve and enhance selected roads throughout the United States. Since 1992, the National Scenic Byways Program has funded almost 1,500 projects for state and nationally designated byway routes in 48 states.”
