Treeffiti?

As someone who's fascinated by language and typography, I'm always on the lookout for interesting signs, words, posters, etc. Yesterday, I came across some 'rural graffiti' on a tree at Symonds Yat in the Wye Valley. It was right by a fairly busy footpath, but why it'd been chosen as a site for names and initials obviously carved over a number of years, who knows. I t made an interesting change though from the more conventional Banksy-style graffiti I'm used to here in Bristol and was every bit as striking, especially in the sunshine.
