In what way did travel underscore for Anderson what she did not want to happen in her own life?

In one such trip, Anderson visited her extended family in the mountains. She paints a picture of their abject poverty and grim futures. She imagines their short lives and the “cardboard boxes” (86) that will be used to bury them someday. At the end of the poem, she designates herself as someone who wants “a coffin made of wood/from trees not yet planted” (86). She wants to live a long and healthy life very different from the lives she sees being lived during her trip to the mountains.
