"Marty grabbed the large flash camera and the duffel bag full of tools and supplies from the Hill Valley Army/Navy Store. Doc grabbed his own duffel bag and led the way toward the hole they'd blown in the hill [using dynamite]."
—From Back to the Future Part III by Craig Shaw Gardner (quote, page 18)

The Hill Valley Army/Navy Store was a store in Hill Valley in 1955 that sold military tools and equipment.


Dr. Emmett Brown visited the army/navy store on November 14, where he bought two duffel bags full of tools and supplies for his and Marty McFly's excavation of the DeLorean time machine from the Delgado Mine.
