Another bloody blank

Joined John for 24 hours, filling in for Pete who was at a wedding. As ever the company was fine, but the fish are absolutely failing to play ball. It rained, only light, for the first few hours, then I spent the whole time watching a territorial swan chase off a game of about twenty, probably juvenile, others. The charade was repeated at hourly intervals, often moving the leads as they swam over the lines. Occasionally the pursuit would become airborne, and on one occasion I was lucky to lose only the terminal tackle, as an aerialised swan ran/flew through the line, dragging the rod off the rest and almost to the water. That was the closest I got to a run.   Took the opportunity to go over my tactics, methods, rigs etc with John to see if there is any explanation for the lack of success. The only one he could come up with was extremely bad luck - in my opinion its reached the stage of ridiculously bad luck!
