interesting idea for a quiz. but biggest fix needs to be listing the national parks that gets you the answer. When you finish you should be able to see what you missed and just listing the states doesn't allow that because I didn't know what park it was in the first place. Also I don't know what national park would get you any of the mid Atlantic states?so those should be gray too. and you haven't updated to include New River Gorge NP in West Virginia. look forward to your improving this intriguing quiz
