Oh dear - what we have to deal with! I obviously should have made it clearer for you - the question was in answer to JT's post (the clue is - that's why I quoted his text) which he did not send to me via PM - ok? I would actually prefer to hear from him when he is ready.
Let me try again - Quality Time need not reply - JT - what about the travelling public and crew and the poor hill walkers on the lump, since we all recognise that (a) (i) is ideal but not universal, (b) (i) is extremely unlikely and (b) (ii) is extremely common? Who's problem is it then? Is that not the issue? Are the regulators being thorough enough in this age of SMS and self-regulation?
