Put a border somewhere and there will come a point when it needs to be crossed. Put two different governments in charge of life on either side of that border and life gets a little more complicated when you need to cross that border.
Take trains, for example. On mainland Europe you can travel by rail through several countries without needing to change. The Venice-Simplon Orient Express runs a service from London to Venice, travelling through England, France, Switzerland, Austria and Italy. Once you’ve crossed the English Channel, it’s the same train all the way to Venice.
But when it comes to the English/Welsh Borders, things could become a little more interesting.
