Spring Mill State park is a little piece of history that is in the heart of southern Indiana. Here you will find a working frontier village. They have a working blacksmith shop, school and a grist mill with saw mill. You can purchase corn meal freshly ground from the mill. You can watch how they cut boards from logs. All driven from a water wheel that is fed by a natural spring that comes from a cave. Speaking of a cave, they have several caves on site. One of which you can take a boat ride through. Near Spring Mill is a town called Mitchel Indiana, there you will find a museum of Gus Grissom. They have items from his mission into space.  This is just a short trip but well work it. Lincoln SP also has an ampitheater where they have events through summer and fall. Check out the IDNR website for events that are happening.
