Unmarked tanker trucks. What are archeologists hauling out in tanker trucks?

I don't know, Mulder.

And where are they going with it?

(consults her map)

That's the first question to answer if we're going to find them.

(stops at a stop sign)

What are my choices?

About a hundred miles of nothing in both directions.

Well, which way do you think they went?

(puts down the map)

We've got two choices. One of them's wrong.

(looks left down the highway)

I think they went left.

(looks right)

I don't know why, I think they went right.

[Look at each other, Mulder stares straight ahead and takes off driving straight ahead on an unpaved path.]

Five years together, Scully. How many times I been wrong? (Scully rolls her eyes) Never. (she looks shocked and amused) Not driving anyway.
