From a match fishing perspective I suppose my all time bogey venue was when I lived in Newcastle and one or two rounds of our local summer league were always on this gravel pit at Longtown near Carlisle. Blanked in my first two matches there, third time had an eel which for some bizarre reason didn't count under the leagues rules, fourth time another blank and then, on the fifth and final match I fished there, started as usual on a big piece of flake cast to the horizon for one of the lake's semi mythical chub which you were told would show right at the start or never. Put rod in rest, tip flew round and I missed it. And blanked again.
More recently it has to be the Slough Arm of the GUC. Back in the 90s when I used to run opens on it I would generally do at the very least OK in what would be a very strong field, and in Winter Leagues there only once finished below second in my section in probably a dozen matches. And then a few years ago we started fishing club matches on it. If there's a wrong end to draw on the day (and there usually is) that's invariably where you'll find me ,and if not, I just seem to be off the pace anyway and can't for the life of me work out why, whether its the feeding, decision making or what.
Having said that, my decision making may have taken an upturn. Hadn't been able to fish for a couple of weeks for one reason or another but had intended to go to our match there last Sunday. Then saw the forecast cold easterly, straight in your face on the towpath there, remembered how it had fished the last time we had those conditions and decided to give it a miss. Good decision ! Winner had one perch for a very generous half an ounce and everyone else was second,,,,
