A Woodbury Dairy Queen came in at No. 5 in the nation for the number of Blizzards sold last year on Miracle Treat Day, a fundraiser in which $1 or more from every frozen treat sold went to the Children's Miracle Network Hospitals.

In 2011, the store at 7450 Currell Blvd. sold 13,767 Blizzards, according to manager Brian Lapinski.

The restaurant placed fifth in the nation and second in the Minnesota-western Wisconsin region behind a Dairy Queen in Mora, Minn.

Overall, Dairy Queen stores in Minnesota and western Wisconsin raised $200,000. Since 1984, Dairy Queens nationwide have raised more than $3 million for Children's Miracle Network Hospitals.

This year's event will take place Thursday at participating Dairy Queens. Proceeds will benefit Gillette Children's Specialty Healthcare.
