By Andy FurmanNKyTribune staff writerJack Cupit – make that Jack “Jack and Cheese” Cupit – said he got his first taste of interacting with crowds as a cheerleader. These days, he drives the Oscar Mayer Wienermobile, which makes an appearance at the Newport Kroger – 20 W. 6th Street – 10 a.m.-2 p.m. – today. “I’m an Oscar Mayer Hotdogger,” he told the Northern Kentucky Tribune. “I drive the Oscar Mayer Wienermobile – a 27-foot-long hot dog on wheels.”And how did that come about? Mayer conceived the idea, and the first 13-foot, steel-bodied Wienermobile, built by General Body Company, hit the streets of Chicago, featuring open cockpits.
