nice!
that trivia question is a ringer though!
let's see.. there's the one from the original movie..
then there's the one that would be left back in time from the 3rd movie (set in 1885)..
then there must be one from when Biff went back in time and gave himself the almanac so he could be rich...
I guess there would have to be another one from when Marty went back in time to stop Biff...
So a total of 4 maybe.. the whole time travel thing always did my head in
Loved the series when I was growing up though!
