It’s a cool morning on a nature preserve owned by Bur Oak Land Trust in Johnson County. I’m scouring a shady hillside with John Rucker and his four Boykin spaniels, looking for turtles. “Find turtle, find turtle,” Rucker calls to his dogs. He turns to me and says, “did I tell you I’m the only person in the world that does this?” When he’s not living off the grid in rural Montana, Rucker travels the country with his specially-trained hunting dogs, helping scientists and conservationists find turtles.
