I love that Boston has a subway station called Wonderland.
I mean, you can actually answer the question in the Disney theme song! (The route does in fact go under land, though the Blue Line may go over hills as well.)
And since it’s the north end of the line, all the direction signs read like this one.
I wonder how many Boston kids have looked for tiny doorways hidden in the walls, or white rabbits hopping through the train stations.
