Manny and I were on the National Mall in Washington D.C. near the U.S. Capital Building when we realized that the sunset that evening was going to be absolutely stunning. We started walking as fast as we could (pulling our rolling camera backpacks behind us), towards the Washington Monument. I spotted a cab driving down the National Mall and flagged him. He drove us over to the grassy knoll just across the street from the Monument. I paid the driver and he helped us get our bags out of the taxi's trunk. We scrambled up the hill, setup our tripods and started shooting before this spectacular sunset had vanished. You will never realize how quickly the sun sets unless you take the time to watch one.
