Tony, winter canal fishing can put a newcomer off for life but never give up.
My advice is, with the onset of winter you will find that the fish will shoal up in the same areas every winter,when you find this is happening,walk the cut on a Sunday morning when there is a match of some sort going on,and,when they weigh in, follow the scales making a mental note of where the weights come from and what species were caught.This way you will be able to build up a picture in your mind of the good and the bad pegs.I fished the G.U.C.
around Milton Keynes for 25 yrs and there where stretches 2-300yds completely devoid of fish,then 6 or 7 pegs stuffed to the surface.Why not keep a diary? a lot of us do.The more you get to know the more you will enjoy your fishing.
P.S. if you do have a look a match dont stand directly behind an angler,half way between pegs is o.k tucked up in the hedge,I'm sure you realise this though .
happy days.
