Curiously, or maybe not so curiously, one of the most interesting things in Disneyland is the surface you walk on. There's always a reason for it. What reason can there be, you might ask? Story. Disneyland's ability to immerse you in its environment is directly tied to how well the story around you is told. Take Frontierland; the ground could have been any number of things that might remind you of the frontier (probably something like dirt). The Imagineers didn't stop at dirt, however, they went so far as to put tracks in the pseudo-dirt. Horse tracks. Wagon tracks. Even cowboy boot tracks. Even then the tracks themselves tell a story. I'm not much of a tracker, so I couldn't really tell you which horse has a limp back leg, but I'm pretty sure that the wagon driver spent a little too much time at the saloon! Next time you visit the Park, look at the ground, feel it beneath your feet and watch it shift and change with the story.
