I find borders interesting. If you look on a map they are normally a solid thin black line, they often go through the middle of natural features, a river being common. I’m only really talking about Europe borders as they are the ones I keep crossing. I am going to ignore that for every thin black line 1000’s of people will have died in years past and 1000’s will die in years to come, boarders are emotional. I’ve not crossed a European border where I have had to show papers unless the border is with a British colony (UK and Gilbralter). I do find that black line amazing. As we crossed one black line from Italy to Switzerland, we drove through a series of what looked like toll booths. The traffic slowed for this. I had within reach my passport, the V5 for Bertie, etc. of course we never even had to stop. What never fails to amaze me if the differences that line makes. One side of it people speak one language, people act in a certain way, the currency may change, the culture of the people, the bands they follow, the clothes they wear, the customs they hold dear are all different to those on the other side of that line only a few feet away. Then there are physical things, the roads quality will vary, the roads signs change colour, the house shapes change. Of course sometimes it’s hard to know you have crossed the line. Switzerland and German nothing really changes, particularly if you cross on a country track where some fields straggle the 2 borders, I’m not sure how that works. Even so how can a line drawn on a map actually make so much of a difference?
