The Lodge at Sun Ranch, formerly Papoose Creek, is about the only eco-resort anywhere that allows hunting, which raises hackles in some circles. But it's the flying around the world in search of green lodging that makes us queasy, and Sun Ranch is as responsible a lodge as you can find in the U.S. The 26,000-acre ranch works with Trout Unlimited to ensure the cleanliness of its drainages, which feed the blue-ribbon Madison River; since Papoose Creek appeared in last year's green issue, the owners have begun work on a new six-room main lodge, made with reused materials and opening in May. They're also installing anemometers to gauge wind power's potential. So when you stretch by the giant stone fireplaces after a day spent catching rainbows (or hunting free-range, organic elk), you can do so with a clear conscience.
