I am an official National Park Service Photographer. A big part of my job is to capture moments of people appreciating our national parks. I am the photographer and the NPS owns the copyright to this picture. It has been made public domain and thus I have the right to give you permission to use it. This image captures the reaction of children as they watch the "Black horse Cavalry" ride away during the sesquicentennial of the Second Battle of Manassas.
