An excellent read! Thanks for that, I really enjoyed it...
Don't worry about those missed bites - chub are ABSOLUTELY infuriating! I can't think of any other fish that can produce such frustration... great big thumps on the quiver tip, you strike into NOTHING! Again and again... and then you tentatively hit a one inch pull that could have been caused by a bit of weed or some extra flow and BAM! the rod hoops round.
Forgive me for waxing lyrical, but Shakespeare wrote of Cleopatra's "infinite variety" when trying to explain her allure... so it is with chub. They seem to have an inexhaustible repetoire or biting without getting caught, which is exactly what keeps us coming back.
(Incidentally, I've heard some anglers, myself included, refer to them in very different language when they're being difficult..)
As you wisely point out in the article, at least they bite in the winter! Here's to more success on the river's before the season closes.
Well done!
