How many National Park Service Sites can you name in the U.S. states of Illinois & Indiana?
https://www.jetpunk.com/users/poptartchase/blog/national-park-quizzes for info on abbreviations used.
Just a suggestion: Either make a brief blog and link it in the description or add a sticky comment in the section below about the abbreviations for these quizzes. I suggest this since I have noticed a few of these quizzes now and it would probably save time on your behalf and allow for less clutter in the description. :)
