The border at the Auchope shelter us indeed marked by the fence.
The huts were erected in the Northumberland National Park after very, very careful consideration was given as to their siting, due to the complexity of boundaries in that area.
The huts were coptered in by the RAF from RAF Boulmer.This much is true.
However, 🤔
It is my personal and clearly prejudiced opinion that some Scots working on your version of the OS may have been pushing the border further south as they have done for a few hundred years. At one stage they even convinced Tory HQ in London that the Roman Wall formed the border. Else why did that Party call for all good English to join hands along the Roman Wall Border to show unity and solidarity with the Scots during their referendum?
My family holds a grudge against the Scots who nicked my great x10 grandfather's sheep. Mind you he seemingly came by 25 Kylie cattle around that period so he obviously won that lottery.😂🤣😁
