Agreed the member's section below Kings Weir really does have an atmosphere, the last season I was on there it just really freaked me out and I've no idea why, to the point I was head down and almost running to unlock and get through that gate one evening.
The only real spooky occurrence I've had on the bank was back when the Ouse was in it's prime and my old fishing buddy and I had access to a private stretch of river, below and opposite a very popular stretch. Anyway, we were camped out pretty much next to each other, around midnight and I said I'd go and have an hour up on the shallows about 100 yards upstream, so I took the rod, net and bucket of bait. Swung out the rig and stood there behind the rod. Ten minutes or so later I just felt this really weird presence behind me, I turned round to see this hooded figure, all in black with the most terrifying fanged skeleton face just stood there staring at me. Instinctively - and this is the only time in my life I've been violent - I launched a strong right hook and down the figure went. Although we both laughed a lot afterwards it was the first and only time my friend took a Halloween mask fishing!
