Sow bugs are the other crustacean that Driftless trout cannot stop eating. These flat, armored isopods carpet the aquatic vegetation in spring creeks, and trout graze on them the way cattle graze on grass -- steadily, relentlessly, and without dramatic flair. This pattern sits in the film of the weeds and tumbles free in the current, at which point a trout eats it with the casual indifference of something that has eaten ten thousand of them before.

Fly Selection: A Decision Tree for Every Situation
Most anglers open their fly box and stare at it like a menu in a foreign language. But fly selection isn't mystical — it's a decision tree.

The Winter Guide: Cold Water, Warm Hands, Willing Fish
Winter separates the dedicated from the fair-weather crowd. The rivers are empty, the hatches are tiny, and the fish feed in slow motion. But they do feed — they have to. And the angler who understands cold-water metabolism, midge biology, and the art of slowing down will find winter fishing not just productive but deeply rewarding.
