I think the words, 'far out in the country', and the fact that Phoenix was a small and very old woman who walked slowly with a cane. But if you're looking for a line, I think the sentence - "She was very old and small and she walked slowly in the dark pine shadows, moving a little from side to side in her steps, with the balanced heaviness and lightness of a pendulum in a grandfather clock" is the best line that depicts a long journey.
