... and really cold weather don't go together very well.
There was slush ice in the river and air temps were in the mid to upper 20's. The furled fluoro leader I was using to nymph fish collected a fair amount ice, which really didn't want to come off.
Had to bend the leader and scrape along it with a fingernail, pressing pretty hard, to get the ice off.
Have never had a problem like this before fishing in freezing weather - but this is the first time I've used fluoro instead of a thread leader in these conditions.
P.S. Didn't stop the fish from eating the fly, but it was a bit annoying. Talk about loading the rod close in.
