Before the 2016 Prairie Days becomes a distant memory, get a Prairie Days T-shirt. The Friends of the Darke County Parks are still offering their commemorative t-shirts for the parks’ biggest festival of the year. The cotton blend shirt is gray with black lettering and comes in youth sizes small, medium, and large; and adult sizes small, medium, large, and extra-large all for $10 each. They also have 2XL size shirts for $ 13 each. These shirts are available in the Nature Center Gift Shop at Shawnee Prairie Preserve west of Greenville on State Route 502 Monday through Saturday from 9am to 5pm.
