On a warm, not so muggy early evening, I boarded a train to The Mall: the only mall I voluntarily seek out. Although most museums were already closed for the day, and I did not plan ahead to find out which ones were actually open, I still enjoyed the stroll by architecturally stunning built structures. I walked around the particularly curvaceous, new (to me) National Museum of the American Indian: the sandstone, water, and landscaping created a sense of tranquility and quiet (even though traffic flowed steadily nearby).
