This US National Landmark was chosen for a day's adventure for our teens when it was raining too hard for other planned activities. The kids weren't thrilled when we decided to go...but quickly perked up as we stepped inside the well-lit guided trails of this underground wonderland. It was amazing; like entering a different world. The tour was a bit hokey, but interesting and we enjoyed every bit of the hour+ adventure. Don't miss this!

I've lived in Indiana for...er...let's just say a long time, yet never knew so much about the history and culture of the "Hoosier State" as we learned with one visit to this museum. The kids really liked the rocks and fossils but I much prefer the info about famous Hoosiers (Jackson 5 costumes!), and the traveling exhibits.
