Go about one-quarter mile to the right of the paddleboat-rental boathouse on the Tidal Basin, at Maine Avenue and 15th St SW, find the exact spot on the path from which you can see the Jefferson statue outlined inside of the Jefferson Memorial across the Tidal Basin. Best done at night with the beautiful new illumination on the Memorial, using a tripod and a telephoto of 100mm or longer. If there is no wind, you will capture perfect reflections of the Memorial on the waters of the Tidal Basin.
