The temperatures are warming up ahead of the Independence Day holiday, and so are the grills. But do you know how much to expect your Fourth of July cookout to cost? The Wisconsin Farm Bureau Federation, as well as the American Farm Bureau Federation, have released their Marketbasket Survey. It's an informal survey performed twice a year by volunteer shoppers. They participate by shopping for 12 different food items that are commonly used in both the Fourth of July cookout and the Thanksgiving holiday. This helps the organizations gauge the food prices across the state and across the country. Cassie Sonnentag, the Director of Public Relations with the Wisconsin Farm Bureau Federation, says prices were up.
