3) Hadrian’s Wall
As I’m sure all the history fans out there will remember, Hadrian’s Wall was built to keep nutty Scots out of the civilised Roman Empire. What a lot of history buffs don’t know, is that Hadrian dug the foundations incredibly deep out of sheer terror.
He got his men to dig down until they hit water, then bail out and dig some more.
On the plus side, the wall is good and solid, but on the negative side: unless England continues to maintain the foundations of the wall the entire country of Scotland stands the risk of completely detaching from the mainland.
This would turn some of the southern Scottish towns into enchanting seaside resorts, but over a series of seasons Scotland would drift off and eventually collide with Iceland. This would annoy the Icelandic people, but more importantly it would make Scotland’s crap weather even crapper, if you can believe such a thing.
Iceland has a gash economy as we all know, and the last thing Scotland needs now is wave after wave of illegal Icelandic immigrants stealing their jobs and eating their haggis.
