much like the winding walk I would do to transferring between the pink and blue lines I would do everyday in Mexico City. Half way through the crazy hectic tunnels you'd pass an Aztec altar they unearthed when they dug the subways out.
And the mural is reminiscent of those that cover public spaces all over Mexico City. This famous one of Diego Rivera's is in a museum, but the Mexico University campus has several that look just like UMass.
So neither are exact reflections, but pleasant suprising reminders of an ancient city and a pleasant vacation.
