Missing/different scene?

I only remember the scene when Helen Mirren asks him about what to do about the dishes, and he says "Leave them, we're getting out of here". Happened just before the scene you remembered. I would love to see a director's cut of this.

Yeah, I remember Harrison Ford's character Allie getting so worked up over his run-ins with store owners, hassles with friends and just bumper car smashing into all citizens in general, that he was set to explode momentarily. Than, finally, from his pickup truck he announced to his family his exotic plan to circumvent the misdirections of contemporary society, by heading towards the most remote, untarnished destination simply by exclaiming (as you correctly recalled), "We're getting out of here". I remember it because Allie was getting postal and it seemed that either he was going to kill people, or else come up with an alternate plan which thankfully he did. It was an important landmark in the story since the early part of the film takes us to the point of no return on the blood pressure scale. But your memory serves you well, and it sounds like you really dug the movie as much as I did. Those were the days when Harrison Ford had a very special gift. It's a pity he lost all of his subtlety the way William Shatner today is just a comical caricature without any of the skills he once had.
