By Ali Schmitz Dozens of vendors lined Charleston's Kanawha Boulevard on Tuesday, offering up signature West Virginia cuisine - pepperoni rolls and craft beer - on the Mountain State's 154th birthday. Rolls on the River, an event celebrating an Appalachian culinary tradition, took place at Haddad Riverfront Park. Vendors from throughout the state traveled to Charleston to compete for the title of best pepperoni roll. The event was a fundraiser for Big Brothers Big Sisters of South Central West Virginia. Hundreds of tickets were purchased to the sold-out event from the nonprofit, which encourages mentoring children statewide. Sara McDowell, executive director of Big Brothers Big Sisters, said she was excited by the large turnout.
