I have been to the NASCAR Hall of Fame a few times now. While it's been open for just 1 year it ranks 2nd of all the sports Hall of Fame's in attendance. The only one visited more is the Baseball HoF, and was opened back in 1939.
Great attraction to spend the day at even if you're not a Fan of NASCAR. You may become one once you visit the Hall of Fame. The staff is amazing. Do yourself a favor and take the time to visit it. It has a movie to view that tells the history that I recommend viewing and has alot of interactive areas for you to enjoy.
