Marty: (continued) ...you haven't heard of him yet.

Doc looks at Marty's feet. He still has his Nikes on.

Doc: Marty, you have to wear the boots. You can't wear those futuristic things in 1885. You shouldn't even be wearing them in 1955.

Marty: All right, Doc, look. Once I get there I'll put them on, I promise.

Doc: OK, I think we're about ready. I put gas in the tank, your future clothes are packed, just in case fresh batteries for your walkie-talkies. Oh, and what about that floating device?

Marty: Hoverboard.

Doc: Alright.

Doc puts the hoverboard in the DeLorean.

Marty: You know Doc, it's gonna be a hell of long walk back to Hill Valley from here.

Doc: It's still the safest plan. After all, we can't risk sending you back to a populated area, or to a spot that's geographically unknown. You don't want to crash into some tree that once existed in the past. This is all completely open country! So you'll have plenty of run-out space when you arrive. Remember where you're going there are no roads. There's a small cave over there which will be a perfect place to hide the time vehicle. Well, the new time circuit control tubes are warmed up!

Doc starts the DeLorean.

Doc: Time circuits on. I wrote the letter on September 1st, so we'll send you back the very next day. September 2nd, that's a Wednesday. September 2nd, 1885, 8am.

Doc inputs the date and time.

Doc: I get shot on Monday the 7th, so you have 5 days to locate me. According to my letter I'm a blacksmith, so I probably have a shop somewhere. All you have to do is drive the time vehicle directly towards that screen accelerating at 88 miles per hour.

Marty looks at the screen. Underneath is a mural of Indians.

Marty: Wait a minute, Doc. If I drive straight towards the screen, I'll crash into those Indians.
