ST. CLOUD - The deep freeze in central Minnesota has meant some brisk business for those who deliver hot food to those who choose not to venture out in the cold.

House of Pizza owner Brandon Testa says he added more delivery drivers over the past few nights.

Testa adds getting to work has been a bit challenging for some of his drivers.

Testa says he also talks with his drivers about being safe in the cold, before they head out with their deliveries.
