Odd scenery
Is it believable or common in the south that you would see a back porch with family members' graves and headstones right outside the door? This is illegal in many midwestern states.
Does this happen in some states? Most states have long required registration, wide boundaries, and other physical barriers for burial sites on/near private residential property. This didn't add any sort of roughened character to the house to me; it just seemed odd and naive.
