Hey ketts, as we all know 80% of fly fishing, unfortunately, is sub-surface. I say that because casting drys to rising fish in my opinion is the best. Anyways, we also know that we must carry a spare spool of floating line in case conditions change. If you don't see rising fish then start out with a searching fly as halibuthitman suggested. Now, if a hatch occures, as soon as you notice rising fish look around on the water surface for trout food. At this point you must discover what the fish are clewing in on: emergers, duns, spinners, terrestrials, etc. It really doesn't matter what time of day it is. A week ago I was catching trout on the Fall River with a dry fly at 1:00 in the afternoon in 90 degrees! For me, this is why I enjoy fly fishing so much. Anyone can sling bait and hardware at fish but flyfishermen must have a keener understanding of natural bug life cycles and then decide at what stage the fish are eating them.:think: It's an adventure!!!
