It’s the annual family day at the Flint Hills Discovery Center this Sunday, 9/13/15.
From their newsletter: Free admission all day on Sunday, September 13 to the Flint Hills Discovery Center! It’s the last chance to view the In the Dark exhibition. Check out the children’s area and Horizon Ranch Flint Hills Immersive Experience Theater Experience. Several local businesses will be in attendance with fun activities for the kids, too!
If you haven’t ever been, you should definitely make the trip. They have all kinds of interactive exhibits that do well at blending entertainment and education for just about all ages that show off the wonders of the tallgrass prairie and the Flint Hills.
