Many years ago my brother in law Chris persuaded me to fish a small lake on a farm out in Essex that was owned by his boss.
The lure was that it hadn't been fished in the 15 years that his boss had owned the farm. Chris picked me up on a cold January morning and we drove over there, had breakfast with his boss and made our way to the lake. Only about half an acre if that but a lot of the bank was unfishable but we found a couple of swims opposite each other where we could fish comfortably and got on with it. Chris set up a feeder as he had the wind blowing into him but I had it behind me so went with a simple 2bb waggler set up to fish maggot in the 6 ft of water in front of me,
All the time it was getting cooler and the sky had a heavy grey look to it, but Chris was off the mark with a couple of decent skimmers and I had managed 3 and a couple of roach around the 8oz mark. Then it started snowing as the wind got up, big old flakes so up with the brolly which kept me well sheltered. Chris in the opposite swim wasn't so lucky though as it was blowing straight into him making it really awkward for him.
The snow got harder and harder but for me at least the fishing just kept getting better as Roach after Roach came to the net, a good stamp too 8ozs-1lb. After a while I realise that I couldn't actually see Chris on the other bank in what appeared by now to be blizzard conditions.
Half an hour later The Abominable Snowman appeared by my side, well it was Chris actually

covered in snow from head to foot and shivering almost uncontrollably, he'd had to give it best as he was being blinded by snow blowing into his face. I reluctantly had to pack up although I was still catching well and had probably had 30-35lbs of fin perfect Roach to that point.
Sadly Chris changed jobs a month later and I never had another chance to return to the lake that had provided a memorable session that's still fondly remembered, at least by me.
