The county’s flat landscape makes it perfect for cycling, with miles of scenic trails to explore. Locals love their sugar beets. No, really. It’s a big deal here.
Ice fishing is practically a religion on the frozen bay. Bay City is the county seat and it boasts beautiful Victorian architecture and a waterfront.
