Thanks for that Hob. I do find it interesting that local 'information' becomes completely entrenched so you wouldn't even think to question it. I was looking for mention of the stone on the internet and I think every single mention repeats the old 'where the king fell' chestnut. But when you try and think about it outside the usual that's just how it is' frame, it's only then it strikes you as being bizarre and a bit unbelievable. I guess it's like all sorts of stuff you believe as a child, when you accept information unquestioningly because of the source you hear it from - it might be years and years later when you're just about to repeat it to another adult as fact, that you finally think 'what the??' and keep quiet.
