This cutthroat, hooked by my buddy and fellow blogger Tim Romano last week on Montana's Blackfoot River did not, as you can see, cooperate for a quick mug shot. But the fish isn't what's important in the photo. Take a look at the thick layer of foam behind the cutty. The trout was one of dozens dimpling through this big swath of clean, rich, frothy goodness we stumbled upon late in the day. While there is no such thing as a bad dry fly eat, I have always found that finding trout and catching them when they're sipping in the suds is a special treat that can be more challenging and rewarding than targeting rising fish in clear water.
