Vilas Cranberry Company

Cool temperatures Sunday night had cranberry growers in northern Wisconsin on frost alert. 

On a chilly night, cranberry bogs can run many degrees colder than the average air temperature on the ground.  Bob Winter runs Vilas Cranberry Company in Manitowish Waters.  He says the mercury would have dipped below freezing in the bogs, if he hadn't turned on water sprinklers to help keep the plants warm.
