Polka Fest has fresh legs this year. For the first time, Michigan-made vodka and Polish beer will be served in Cedar. Native son Rifino Valentine, who developed the wildly successful, high-quality Valentine Vodka spirits brand in Detroit, will return “home” and toast to his roots. Cedar has an energetic new booster in Kathleen Bittner Koch, a 37-year-old Hamtramck native who moved here five years ago to buy a farm.
