Rock Creek was on fire. My wife and I could see the smoke in the distant hills, and we could smell the burning timber whenever the breeze stirred. We were in Missoula, Mont., last week on assignment for Field & Stream, and we'd planned to fish Rock Creek as part of the story. But the blazes had forced officials to block access to the river, and as our plane took off Tuesday morning, headed back toward the East Coast, I could see the red glow of the flames in the mountains. The fire has since burned some 15,600 acres, and it's nowhere near contained.
