Just in time for summer — and the blazing heat — the Maryland Agriculture Department has created the Maryland’s Best Ice Cream Trail. The trail consists of seven creameries that produce fresh ice cream and sell it to visitors on the farm. The creameries are Rocky Point Creamery and South Mountain Creamery in Frederick County, Prigel Family Creamery in Glen Arm, Broom’s Bloom Dairy in Bel Air, Kilby Cream in Cecil County, Misty Meadows Farm Creamery in Washington County and Chesapeake Bay Farms in Worcester County. Anyone who visits each of the seven creameries before Sept. 7 will have a chance to be named Maryland’s Best 2012 Ice Cream Trailblazer — and win ice cream.
