Joshua Foer, Dylan Thuras and Ella Morton are on a mission to make you rethink where you travel. Their new book, "Atlas Obscura," is filled with hidden gems to explore throughout the world, from a Portuguese church decorated with bones and skulls to the sparkling glowworm caves of New Zealand. In this hour of Forum, the three authors, who also run the popular Atlas Obscura website, tell us about unknown wonders worth seeking out. And we want to hear from you: What's your favorite obscure landmark or place?
