Here is the situation. Fished today on a free stretch of water. A guy arrived whilst I was worming, and took up the best fly fishing part of the beat. No probs. An hour or more later, I decided to get my fly rod out, and politely asked him if he would mind if I fly fished down the run. He refused and suggested I fished the next run down (it is not so good). I was polite and did not make a scene - but I think that he was way out of order. In his position I would have said "yes have a go". Even though this was not in Scotland, I thought that the Scottish "cast and two steps" is the sporting thing - or am I wrong? Is it OK to sit on the best run for hours, waiting for the fish to run through?
