Even back in my match fishing days I never felt the need to keep any methods secret, except maybe for team events, then everything was shared between your team mates. Venues on the other hand I can understand. I've seen too many places ruined by giving info about a place. Two spring to mind, one, free fishing on a small river in North Yorks. My mate and I didn't have transport at the time, and got another mate to take us in his van, on the promise that he wouldn't spread it about. He lied, and it became so popular that the farmer stopped anyone from fishing it. Free fishing on a stretch of the Nidd was lost because someone spread it around, and some berk left a gate open and the cattle got out, and wandered through the village. That one was particularly annoying because we got to know the family very well, and took their son under our wing, brought him bits of tackle, and showed him how to fish the place. We all felt a bit proud when he got his picture in the Yorks Post, with a 6lb chub he'd caught. The family were as upset as we were when they let us fish it one last time before they closed it, and leased it to a syndicate.
