“LETTUCE” take you on a tour of Michigan, starting at Revolution Farms in Caledonia, where they’re transforming how leafy greens are grown! Then we’re off to the Straits of Mackinac to explore an 18th-century fort and fur trading post. We head to the Upper Peninsula for a whimsical walk on the “Narnia Trail” in Cedarville. Finally, we travel to the Beaver Island for an Emerald Isle adventure.
