This past Saturday, fans of all ages gathered on the lawn of the Gamble House in Pasadena, continuing 2015's 30th anniversary festivities of Back to the Future. The Craftsman style home designed by architecture firm Greene & Greene was the exterior location of Doc Brown’s 1955 mansion in the film. (The interior of Doc’s house was that of the nearby Robert R. Blacker House, also designed by Greene & Greene.) Fans of the film dressed up like their favorite characters, toured the home’s interior, snapped photos with about a dozen DeLoreans, and watched Back to the Future on the lawn after the sun set.

Make sure to set your time circuits to this October for our full coverage of the five-day Back to the Future event We're Going Back, which will feature BTTF trilogy screenings at the original filming locations, hoverboard riding, cast and crew Q&As and much more.
