The DeLorean on the dirt access road leading to Twin Pines Ranch.
A dirt access road was the means of reaching Twin Pines Ranch, home of the Peabody family, in 1955. The entrance was bordered by bushes on the left and a chain-link (or diamond-mesh) fence on the right, to which was affixed a sign bearing a color illustration of two pines trees and the name TWIN PINES RANCH in large upper-case letters. A smaller sign reading BEWARE OF DOG was attached to the first fence post.
Marty McFly made use of this track to make a hasty departure from the ranch in the DeLorean time machine when Otis Peabody opened fire with his shotgun, due to Marty's yellow radiation suit and the DeLorean bearing a close resemblance to an alien and a spaceship featured on the cover of Mr. Peabody's son Sherman's Tales from Space comic book.
