Section 4-3-2209 - Welcome centers and rest stops - Development of promotional content and training(a) It is the intent of the state to promote and facilitate Tennessee's natural beauty and bountiful attractions. To the extent permitted by federal laws and regulations and the requirements of the federal highway administrator, all welcome centers supervised by the department may have photographs, posters, maps, music, books and other items that illustrate Tennessee's unique heritage and wealth of endeavors, from the historic to the peculiar, the traditional to the frivolous. Each welcome center may place an emphasis on events and sites that are within a fifty-mile radius within Tennessee.(b) The commissioner of tourist development shall develop promotional content and train staff members regarding all aspects of Tennessee life that are endearing to its citizens and captivating to its visitors. Emphasis may be placed on hidden treasures that a casual observer might miss, including natural sites such as waterfalls and caves, and man-made sites such as museums, seasonal events, and community celebrations. The commissioner of tourist development is encouraged to make Tennessee's welcome centers a place for travelers to enjoy and linger as tired limbs are stretched and eyes are rested.
