"Drake Emerger" Pen and Watercolor. The last evening of the trip was by far the most productive fishing dries. After the sun went down, we switched to an emerger and started back down river. Fished the emerger down and across on a swing. Corey expertly cast the emerger in a spot where he was earlier rejected while fishing a dry. The first cast in the area resulted in a nice brown. Persistence pays off.
