Dave, my point was less about exclusivity as noting that there are already (IMHO) sufficient routes for cyclists to use in the Meadows area to cover all potential through-journeys quite well.
I do use the canal towpath frequently, on bike and on foot, and it often feels like walkers get a bum deal. JW is wider and doesn't have a metre of water to risk falling into, but I also don't see the benefit to making all paths shared use just because we can, unless we can also include demarcated lanes for cyclists and walkers (since not all cyclists seem to use their brakes); I don't feel under threat or "in the way" when I walk up MMW or LW, and I enjoy the quiet time free of whizzing cyclists when I walk from Melville Drive up to Bruntsfield Links.
But on my earlier post about the bones, which I can't edit because it was more than an hour ago that I wrote it in a necessitated hurry, I would like to see the jawbones cleaned up and restored - not just as the relic from the exhibition, but as a reminder of a crueller age, my feelings on which this post is too narrow to contain - and so paradoxically I would also like to see them removed and destroyed for that same reason.
I would actually rather see a stainless steel structure in the same vein as the Gateway Arch in St Louis; something akin to a modern take on the shape, themes and form, and a gateway to The Meadows. I would further like to see counterpart gateways at all the other entrances to The Meadows, each relevant to the foregoing names.
