New Braunfels' 19th annual Battle of the Blizzards, a sweet, longstanding tradition, is returning on Thursday, July 30.

Each year, on Miracle Treat Day, participating Dairy Queen locations donate $1 or more from every Blizzard Treat sold to Children's Miracle Network.

In New Braunfels, local high schools help drive sales of the treats by competing to sell the most Blizzards in one hour.
