LAKE FLORIDA, Minn.—In 1924, Bob Dickerson’s great-grandfather went on a fishing trip. His doctor had told him he’d breathe better if he spent some time on Minnesota’s lakes, and so he arrived at Lake Florida not far from Willmar, where a farmer kept a bunch of rowboats in a cow pasture. Dickerson’s great-grandfather, Jens, caught a slew of fish, watched the sun set, listened to loons and camped. The next day, he bought that pastureland. He soon built cabins, renting them for $15 a week.
