The Back 40 Museum is both a whimsical and a serious place (kinda' like life). As you explore the museum you will typically encounter many fanciful exhibits which are essentially just interesting "fluff." They are merely intended to give the visitor a pleasant, and more or less, mentally effortless pause. These exhibits are viewed in a way similar to the way one would view a magazine as you casually flip through its pages while waiting for your turn to get your hair trimmed.
On the other hand, the museum also involves some much deeper intellectual and emotional waters. Many of the articles, essays, short-stories, and books that you will find in the reading rooms are not at all "fluffy." They have some serious and universally important stuff to say about the human journey. Especially in Reading Rooms 1, 3, and 4 is this true.
So, you choose - fanciful or serious. And, please know that the Back 40 is constantly expanding and changing its exhibits, making the museum a great "come-to" place for repeated and leisurely explorations. Do come often and stay long. Observe, read, ponder, laugh, be challenged, and surprised, and informed. The Back 40 - it's just a great place to wander. And, it's plenty big enough to do so for a long while.
