I was 'persuaded' to have a days fishing at the Woodlands complex near Thirsk a few years back and caught a few of the Barbel that, unfortunately, have to exist in the place. They were in very poor condition and a very washed out pale colour. Now whether this was because they simply didn't take to living in a puddle or because they had been caught a dozen times that week I wouldn't know, but I truly found it a disturbing experience fishing there and will not be going back in a hurry.
I'd noted early on in the days 'fishing' that a decent fish was alive and tethered to one of the vast array of floats lost by other 'anglers' amongst the foliage on the Island in front of my peg and duly pointed this out to the owner/money collector relieving me of the extortionate day ticket sum, hoping that he would assure me that a boat would be launched at the end of the days 'sport' to free the unfortunate fish. The look on his face spoke volumes.....poor fish.
