The speaker is travelling along a highway and seeing the land around it as hurt, a place marked by damage. The road feels like a gallery, but the things on display are "empty eyes," so the journey becomes a kind of walk past vacant faces or hollowed-out views. There's a sense of looking without really seeing, and of being looked at by nothing.
The third stanza pushes further into unease. The speaker is heading into land "that nobody should know," which suggests somewhere shameful, forbidden, or best forgotten. Then the last lines twist a word: "somewhere" swells into "somewhore." The sound change is jarring and crude, and it hints that the place has been used or degraded, as if a neutral location has turned into something sordid. The poem doesn't explain this, so the reading is open.
The mood is bleak, uncomfortable, and quietly disgusted. Short lines and bare images leave the reader feeling the emptiness, with the ugly final pun landing like a sudden sour note.
