Cornfields and cows? In the Midwest, there’s that. But when adventurers set out for Road Scholar Retreats across America’s breadbasket, there’s also lots of learning and discovery. Hear the tremolo of a loon while canoeing Minnesota’s gem-blue lakes. Bike the Black Hills and learn about Native American life in South Dakota. Stitch an Amish quilt in Indiana. And remember: The treasure in these laid-back settings isn’t just the learning — it’s the new friends who won’t soon be forgotten.
