While our Interstates all seem to look and feel the same, Route 66 is always changing. In 2001, when Route 66 turned 75, author and Route 66 Road Warrior Michael Wallis traveled the Blue Highway to document the changes to Meramec Caverns, several drive-in theaters, the Totem Pole Park, the Blue Wale, Round Barn, Big 8 Motel, U Drop Inn and Pop Hicks Cafes and more.
