Horse Cave, Kentucky, transformed from a waste dump into a tourist destination thanks to the modernization of its sewer system and the cleanup of Hidden River Cave. Former Mayor Sandra Wilson faced resistance to new sewer fees but ultimately succeeded after 40 years of advocacy, allowing the cave to open to visitors in 1989. With an investment of $6 million for infrastructure, the cave now attracts 30,000 tourists annually and features the world’s longest underground suspension bridge. This revitalization also spurred local factory growth, employing 3,000 workers.
