We were lucky enough to see about 5 deer grazing near the stream. They seemed unperturbed by us.
We freshened up witha swim in one of the outdoor swimming pools that are scattered around Reston for the residents to use.
Later in the day we made a visit to the second centre of the Smithsonian Air and Space Museum which is based near Dulles Airport.
There were a multitude of planes and spaceships to see.
We saw one of the retired Concordes.
