In reply to Ron Rees Davies:
> There seems to be a superstition amongst "weekend warrior" hillwalkers that it's a noble tradition of the hills to add a stone to every cairn you pass, and this has been reinforced by certain TV hillwalkers doing it.
I suppose when I was doing a lot of hillwalking I was a "weekend warrior", because I was in school during the week. But the tradition was certainly well established 35 years ago.
> In part I suppose it could be thought that the cairns mark the paths when there's snow on the ground, but it's unlikely any of the people adding stones ever trailbreak paths through unbroken snow cover.
Wowzer - such fantastic snobbery. But yes I certainly did that, though the times I was most grateful for cairns was in thick fog/driving rain, or as we called it, normal weather !
> It's such an issue that in some places the National Park Authorities are having to consider costly cairn removal schemes.
Really ? Which national parks ? Because as far as i am aware they are all too cash-strapped to do anything of that nature.
