SECTION 1. WAYSIDE EXHIBIT AUDIO DESCRIPTION
The text and image content of each new wayside exhibit is most often a custom design to tell a specific interpretive story at a specific site. Audio description enables visitors who are blind or who have low vision to enjoy and make meaningful connections to national park site resources. Audio description provides an audible narrative that reveals not only the content of each wayside exhibit, its text and images, but also describes what sighted visitors see in the surrounding vistas.

Actual recording of the description of each site and each new wayside shall be done after installation, so that the audio describer is working from what actually exists for sighted visitors. This requires travel to the actual sites where the new exhibits have been installed.
