I just realized that in the first Back to the Future movie, when Marty time travels for the first time, he's in the lot of Twin Pine Mall, but when he arrives in 1955, he's on a pine tree farm that's the name sake of the mall and while he's driving away from the farmer who's shooting at him, he runs over one of two pine trees at the farm's entrance. So when he comes back to 1985 to the same parking lot at the mall, it says "Lone Pine Mall".
