The Dairy Queen system is offering up a sweet deal to say thanks to fans and to celebrate the first day of Spring.

On Monday, March 20, the first day of spring, the DQ Grill & Chill restaurant at Business 151 and South Water Street in Platteville will host Free Cone Day. Fans will enjoy a free small vanilla soft-serve cone with the signature curl on top (limit one per customer while supplies last).

During Free Cone Day, the DQ Grill & Chill restaurant will also accept donations for a Children’s Miracle Network Hospital. CMN Hospitals raises funds and awareness for 170 children’s hospitals across the U.S. and Canada.
