One of my favorite movies of all time is Shawshank Redemption with Tim Robbins and Morgan Freeman. If you haven't seen this movie you should. Those of you that have seen this movie should get this one quickly. You are looking for a smallish medium container in a pretty obvious spot. This item played a key part in Andy Dufresne's well devised plan.
By the way if you didn't know Shawshank Redemtion is from a short story by Stephen King that was adapted into a screenplay. LIke this cache it is a pretty easy READ. This cache is placed by permission. There is nearby parking and bathrooms at the Elkton river front park nearby.
