Put it in the present tense - 'see off the bus' - but, no, it's not that one. I've no thoughts about that Langley stone beside it's 'in the right place' and upright. But it would crush a wheelbarrow - and it's unlikely I could have any claim of ownership on it!
I'm trying to inveigle Aron to come and visit the Blackstone - that'd put science on its head, if he did. My four-poster outside of Alston, with two pairs of outliers and a little barrow, has never been checked over. (The weather was too poor this summer for the four mile hike). There is a chance that it will have cupmarks, or something, somewhere.
