March 30, 2017 DigiDoc; Horsies! This digital image depicts an important part of the family activities that Rock Creek Park houses. One of the many centers for recreational activities that the location includes is this one: the horse center. I chose this specific picture for the center because I feel like it transmits what most of the Rock Creek promotion theme is: a space for family enjoyment. What better way to sell a spot than kids on horses? It would sell me, for one.
