We gon' need more tracks.
Doc:This spur runs off the main line three miles down to E3. There's a long stretch of track that will still exist on June 9th. This is where we'll push the DeLorean with the locomotive. Funny, this map calls Clayton Ravine "Shonash Ravine"... that must be an old Indian name for it. It's perfect, a nice long run that goes clear across the bridge over the ravine to the, you know, over near that E3 conference center.
Marty McFly: Right, Doc, but according to this map, there is no more bridge.
Marty McFly: Well, Doc, we can scratch that idea. I mean, we can't wait around a month for this thing to get finished.
Doc: Marty, it's perfect, you're just not thinking fourth-dimensionally!
Marty McFly: Right, right. I have a real problem with that.
Doc: Don't you see? The bridge *will* exist on June 9th. It's safe and still in use. Therefore, as long as we get the DeLorean up to 88 miles per hour before we hit the edge of the ravine, we'll instantaneously arrive at a point in time where the bridge is completed. We'll have track under us and coast safely across the ravine!
