Yesterday night we drove up to Washington D.C. for our grandmothers 80th birthday and a family reunion. Today we went to Great Falls, VA for a picnic.My mother used to go there as a child when she lived outside of Washington D.C. Great Falls is a series of waterfalls on the Potomac river. We learned that George Washington surveyed there and helped build a canal that he believed would help with trade to the western frontier. It was very beautiful, and we got to climb on some rocks by the river. After that we went to the new Smithsonian Air and Space Museum. It had a lot of famous planes, such as one of the bombers that dropped an atomic bomb on Japan.
