Terminology is definitely one of the difficulties that Park Advocates have in all aspects, from both the light-hearted (like these quizzes) to even the most serious issues. I have yet to see anyone come up with a good solution for how to handle the fact that the word "National Park" refers to both any one of 58 "National Park National Parks" and refers to any one of 391 "Units of the National Park System." Unfortunately, "National Park National Parks" just sounds goofy, and "Units of the National Park System" sounds stilted.

But yes, it looks like Acadia needs to update their claim-to-fame as being the "oldest" National Park East of the Mississippi - but not the "first."
