Wednesday, March 20 marks the first day of spring, which is cause for celebration—and Dairy Queen's doing so in the best way possible: free ice cream. That's right, DQ is giving away free soft-serve cones today. Happy Free Cone Day, everyone! DQ fans can order a free small vanilla soft-serve cone with the chain's signature curl on top at participating non-mall DQ and DQ Grill & Chill locations throughout the U.S. Each customer is limited to one cone, while supplies last.
