Nate and I started the weekend fishing in the rain. Any further west and we would have been fishing in the snow. I think rain turns fish on. Perhaps it triggers them to eat before the water turns dark and turbid and eating becomes difficult. The front end of the rain produced some steller fishing. Sure enough, the next day many streams looked like Wonka's chocolate river. So we fished streams that run clear regardless of how many inches of rain fall. It's good to know your Driftless options.
