Who says there's nothing to see in Iowa? The Amana Colonies are comprised of seven villages that preserve and track the settlement of the Inspirationalists, a religious group from Germany.

A desert in Maine? Sort of. The "Desert of Maine" is the remains of a failed agricultural effort that saw massive erosion wash away the soil and uncover a floor of sand-like glacial silt. Despite its name and appearance, the 40-acre area does receive plenty of rain-so its technically not a desert-and the surrounding forests are slowly shrinking the "desert's" size. Still, these factors make it even more interesting, and the natural anomaly is an interesting stop on a journey through Maine.
