I will be going!
Next month, so get ready.
the Friday before classes begin on Monday.
Thousands of classes.
They give a printout with open classes with room.
You can get credit, or can just sit in class as a "hearer" "auditor"
Also gym classes, horse, dance, archery, pistol, rifle, track, run, swim, gymnastics, etc.
Can look at preliminary schedule at http://missouristate.edu
But some classes may fill up before free students enroll.
So I wait until they hand me the printed schedule of open classes.
