Left Lynnhaven around 8 AM and headed south to False Cape. Then the fog set in. Visibility was down to 50 yards, so the plan of looking for flocks of gannets was called off. Decided to troll (I know its horrible) until the fog burned off. The radio started to buzz with lots of people catching fish. Used the radar to find the nearest crowd of boats and found our own school of BIG stripers under gannets. I had never seen stripers acting like this. Usually when I see stripers on the surface, they are aggressive, but these fish were lazily swirling around the surface. I missed a couple strikes using a small bunker fly, and then my splicing connecting my running line to my T-14 failed and I lost my sinking line rig. I gave up fly fishing after that and headed in. I think my problem was my fly choice. While I watched my T14 sink to the bottom, I noticed what they were feeding on and it was 1-2" silversides. I'll have to notice things like that next time, and be more prepared with backup rigs.
