Chris and Karol Kirk of Madison, walk through Clifty Falls State Park on Monday. Karol Kirk said they use the park every day of the year to bike, hike and walk. "It is a wonderful resource," she said. "And we seem to have it all to ourselves through the week." The park now has free admission on Monday through Wednesday, with regular admission prices on Thursday through Sunday. (Staff photo by Ken Ritchie/kritchie@madisoncourier.com)
