 In regional headlines, hundreds of Minneapolis park employees are set to strike in just a few hours, and Fourth of July is one of the busiest days for the city's green spaces. The union, representing more than 300 employees who keep parks clean and safe, say the city's latest contract proposal lacks sufficient wage increases and hazard protections. This all comes after seven months of failed negotiations. The union has a barbecue this afternoon, followed by a rally and a picket this evening. Kari Spencer has the story at NPR News.org.
