The Time Space Continuum is Cracking up! Just like when old Biff hit young Biff on the Head with his cane!
In reference to this post, Here’s a pickle for you: So if Doc went back to the old west in Back to the Future 2 - where at the end of the movie when Doc writes a letter to Marty - in the beginning of Back to the Future 3 - he reads the letter to Doc of 1955. So - after the events at the beginning of BTTF3 - did Doc of 1985 who was now living in 1885 know that he was going to end up in the Old West since 1955? What do you think?
