After running their wildly popular Juicebox business out of a tiny trailer at the Red River Farmers Market, Renae Cartier Mitchell and her kids have taken the next big step by opening a brick-and-mortar in West Fargo. The public is invited to an official grand opening Saturday, Dec. 4, from where they can indulge in BOGO smoothies, order a "Healthy Hot Chocolate" or smoothie bowl, and check out Juicebox's new, eco-friendly glass packaging.
