Just steps from the shoreline of Lake Mille Lacs, Mary and Rich Dunn look out on a million-dollar view of water, woods and wildlife.
Deer, wild turkeys and loons are plentiful. The retired couple sometimes spot three kinds of woodpeckers before breakfast.
But the creature they have most in common with is a turtle. The Dunns, too, carry their dwelling with them, but their "shell" is a 34-foot fifth-wheel camper with a fully equipped kitchen, electric fireplace, a TV to stream their favorite shows via their Wi-Fi hot spot, and a cozy queen bed.
"It has two rooms so we can separate," said Rich.
"Sometimes we need a door between us," added Mary.
From May through October, the Dunns, great-grandparents in their mid-70s, live in a series of Minnesota state park campgrounds, volunteering as camp hosts. While their RV provides the conveniences of modern living, they prefer spending their days outdoors — hiking, bird-watching and savoring steaks or brats cooked over the fire.
"I could sit out in the woods the rest of my life and be happy," said Rich. "We are building memories."
The Dunns are among roughly 100 volunteers, mostly retired Minnesotans, who commit to spending a stretch of at least four weeks a year as camp hosts. Under the supervision of the Department of Natural Resources, they take on chores and responsibilities that occupy 20 to 30 hours a week.
