Borders, borders, and borders

Interesting. In the United States we travel from state to state without thinking much about the border. If you are on vacation, you might take a picture of the sign that welcomes you to the new state, but that all there is to it. In Europe, the borders are different. Although the countries are smaller than many states they have firm, uncrossable borders. The border between Ukraine and Romania is electrified, barbed wired, and about ten feet high. And every several kilometers there is a little border station, where there is a little border guard with a big gun.
