Recently there was long thread about the BCA. I can now post possible answers to some of the questions, such as "Why is the BCA still raising membership prices when there is a significant amount still left in its coffers?"
Indeed, but appropriate baggage for a silent vigil? I guess placards are 'silent', but does anyone really read placards anyway? I used to have the Shaker Maker 'hippy' model set and one of those had a placard, and that's kind of where I view them.
The question least asked is 'Why now?' There is a wide variety of imitative behaviour occurring and this is just another example from everybody trooping to Durclle Door to a protest about something that happens sadly far too frequently.
