Nice bag Dave, looking back at the cold weather we have had recently I must have become a "southern softy", as I can remember fishing when it was so cold that when you sat on your then wicker basket, your waders froze to the ground.
Even in the coldest of weather a few roach & dace would oblige. I fished a 50 peg Fur & Feather at Willington, where 20lb of roach wasn't even enough to get a prize, and I think there were at least 25 prizes.
