"Roberts Drake" Pen and Watercolor. I just returned home from fishing the Au Sable River in Michigan. The next six fly installments are the flies that I fished with during the trip. There was a lot of rain, so fishing was off a bit from previous years. although conditions were a bit tough, I had a great time fishing with my buddy Corey and the rest of the regulars who make the trip every year. I fished this drake pattern in the evening when the drakes were coming off the water. There is nothing like experiencing squadrons of drakes looking for a mate.
