When we were little girls, our mom flew us to D.C. solo to spend the summer with our grandparents. We were about 10 years old and loved to stay in the basement alone; we would run into bed at night, imagining ghosts and monsters that lived under the stairs. Our grandparents had an amazing backyard, very unlike our flat acreages of grass. They had hills and layers and trees taller than their two story house. They even had a stream in their yard, complete with a bridge! It was a childhood dream to play back there for hours.
