Walking through the gates of Frontierland, my one-track mind often turns to this opening day attraction. While the Mark Twain technically belongs to Frontierland, its unifying power is unlike any other attraction in the park. (Submarines, I’m looking at you.) As ridiculous as it might sound, out of all the things I love about the Mark Twain, its ability to live in two different lands with such grace and ease is my favorite.
