RAVENNA, Neb. (AP) – Fire destroyed a building at a central Nebraska vineyard. Ravenna Fire Chief , DeWayne Thomsen, says crews went to the Cedar Hills Vineyard near Ravenna early Thursday to find the building “completely burned up.” Thomsen says he believes the structure was a utility shed where owners Clay and Heidi Schutz produce their wine. The Schutzes said in a Facebook post that their winery/production building and guest house were affected by the fire. They say the tasting room was not harmed. The Nebraska State Fire Marshal is investigating the fire’s cause.
