to be honest paul, ive just joined the same club i raced in 25 yeaqrs ago.......and to me there is virtually the same number of members in it as there was then, altho there is a few who never send to the races for whatever reasons.
i do see tho every week in the pigeon weeklies that fanciers are packing in and selling up, and i do know pigeon keeping/racing is in decline like you say.
