KAUKAUNA — When Kaukauna voters go to the polls April 5, 2016 to elect their next mayor, they will choose between incumbent Gene Rosin and newcomer Marty DeCoster. Kaukauna Community News asked each candidate five questions about their views on the main issues facing the city. I would have to say, my biggest contribution to the city so far, is bringing a successful festival back to Kaukauna again Electric City Experience is exactly what it is, experience Kaukauna.
