Perched alongside a dusty highway stands the Treasure Spot road sign. Its purpose? Quite simply, it marks a specific location rumored to be a spot laden with hidden treasure. Or so the story goes! The origin of this quirky sign remains a mystery. Some believe it was planted by a cheeky local as a practical joke, others say it marks the location of a long-lost treasure chest, buried by pirates who had mistaken the highway for the coastline.
