Spelunking and caving remains in Lewis Lamon’s blood.“I can remember being in a cave when I was a baby,” he says, his eyebrows lifting in astonishment. “My parents would send me down a little crawlway to see if it went anywhere.”Today, the man who is the property manager for Cumberland Caverns still goes beneath the ground nearly every day. For Lewis, caves are one of the few places that represent a certain forgotten wanderlust, the idea that beneath the earth there exists a subterranean world awaiting discovery, if only we had the passion (or courage) to explore the darkness.
