I am planning on taking the Paris Karlsruhe TGV soon.
I am an american Citizen and i was wondering how it works.
Are there any controls other than tickets. I hate customs and the questions they can ask you at times.
I heard that Germans can be rough.
I want a hassle free trip. I am only going there for one day or two.
FYI I am not a smuggler so please don't get paranoid or joke about my question.
