The Great American Read on PBS

Are you familiar with The Great American Read?  I was not, until I saw it advertised on PBS.  I checked out the top 100 books on the list, and was surprised by some entries, and assumed others would have made the list.  Not sure what my favorite book would be, but To Kill a Mockingbird is right at the top of the list.  Watch PBS?  You can vote.  I have.
