Wow, glad that's still there, how far back did it go? I wrote in it a few years ago. Hard to imagine an unattended visitors book lasting long at many sites over here....
I don't remember how far back it went, I"m afraid, but there were TWO books in the dolmen.
I thought someone had left their homework or a geocache! No, it wouldn't last a second over here. Some pissed up scrote would wipe their arse on it or burn it 'for a laff', wouldn't they.
