Hiked/biked back to Cresent lake with my float tube yesterday and had not fished this in many years. My last trip (11 years ago) was not too shabby from shore, so this time I wanted to get out on the lake. There was some really nice grayling surfacing, but I could not get a single strike all day. Threw all sorts of dries at them and even some nymphs...nothing! Anyone out there know what is needed? Many thanks!
