Jack frost finally arrives

The Trout season seems to be long gone now, a month today it closed it's doors. Today saw a touch of frost on the ground, one of the first frosts this year. Grayling tend to be a species we link with cold frosty days so it was off for a few hours to see if they were biting. It wasn't till after mid-day i got there , i was glad to see a tad of clarity in the water although it was far from clear. So it was on with a glister nymph and a size 12 dry, i scaled down my nymph today to a 14 , and to cut a long story short that was the fly of the day , although i wish I'd spent a bit time at the tying bench prepping some nymphs with a bit more sparkle armed with them i think i could have had a busier day .
