The comments in my latest posting were not directed at you, IWere.

On Satchers' point, I don't know enough about the topography on the other side of the Wall (it's too difficult to get to from where I live, you see) to comment on the convolutedness or otherwise of Michael's proposed routes. But I assume that he at least thought that significant numbers of people would find them useful. On security, I agree any new route would need to have that 'designed in'. I see Michael suggests CCTV.
