Living in the Great Smoky Mountains National Park area, we have an annual tour to view the amazing synchronized firefly event. It’s a spectacular sight to see!

My first encounter with a firefly was in Corfu when l woke in the night to see a tiny light swirling above my bed. It frightened me as l didn’t know what it was. I soon found out. Fascinating!
