In the summer before I started high school, my grandpa picked me up every Sunday afternoon. We would coast down the blooming hills, valleys, and countryside along the lake in his 1968 convertible. My best memories are of listening to old Elvis songs and stories of my grandfather’s high school days. What is the setting of the story? Grandpa’s car The 1960s The lake High school
The countryside would be the setting in the situation. But if the options you listed after the question were the only options you could choose from then the setting would be Granpa's car because that is where they were in the story.
