You are correct, Jennifer. This article contains all kinds of National Park Service (NPS) sites, as I said in the intro. Those are, however, considered “national parks” just because they’re managed by the NPS, even though they don’t have those exact words in their name. The NPS on their website says that their sites are often referred to simply as “parks.” It’s just a matter of how broadly you apply the definition. In this article, I’ve used the broadest possible definition of what national parks along Route 66 are.
