In 1955 the location of the Twin Pines Mall is a ranch owned by a man named Mr. Peabody. He makes the mistake of confusing Marty, Doc and the DeLorean for a U.F.O. and a martian.
As Marty is driving away so nobody gets killed he accidentally runs over one of the two pines outside Mr. Peabody’s ranch.
The ranch was named after those two pine trees. Twin Pines Ranch.
While in 1955 Doc reminds Marty that any of his actions will have serious consequences and could possibly change the future.
