My pal and I recently visited Argal lake in Cornwall to resume our course fishing following a 7 year gap, we found a spot on the bank and started to settle down there but were soon approached by an angler telling us we could not set up there as one of his lines were not far from where we were. His actual swim was some 200 years up the bank. He had walked 150 years down the bank before casting and then playing out line to where he was sitting. In effect he was taking up about 500 yards of the lake bank. If this is an accepted system in this day and age the vast lake would be fished by probably a dozen or so anglers and all others could go to blazes. Acceptable or not. I ask the question.

Well if i was in that situation i would told him were to go.
there are a few people like that on the lakes i fish just gready but i love it wen they blank nd i bag up

If he produced tickets for the pegs he was covering then I might have considered it.
But I did say might.
