i have 4yrs worth of hooks in tub, all my old line goes in the incinerator when i burn my waste paper (can't be recycled due to a silicone coating :[ ), safest way i know, haven't yet decided how to get rid of the old hooks, did consider a small bottle of acid and dropping them in!
was walking of worthing pier today and some kids had just left, fishing not 5 foot from a bin. the buggers had left 2 bags worth of rubbish and 3 hookless rigs. which i binned. tomorrow i will have a word!
