We get our wintertime adrenaline fix at Snow Snake in Harrison with some Snowtubing. Then, we'll keep it chill and slow things down for a majestic horse-driven sleigh ride at Fantail Farm. To warm things up, we explore the city of Port Huron on a warm summer's day? We'll also see rare color photos of the building of the Mackinac Bridge and grab a bite at Max and Emily's in Mount Pleasant.
