The main idea (theme) is that it is a pleasant place where the sidewalk ends, better than the rest of the street and sidewalk. He also hints using the picture that it might be a scary place. He used couplets, and metaphors well (e.g. to cool in the peppermint wind; wind isn’t peppermint, but it is cool and fresh like it). The poem uses couplets that rhyme and the poem is from the point of view of the narrator.
