And I have come back.
Yes, I really, really, did go through Hell.
On a train.
Here's the proof. Here is a picture of Hell. Actually, this is is the train station.
If you ever land at Vaernes Airport, the airport serving the city of Trondheim, you can get a train from the Airport to Trondheim Central which takes about 45 minutes, and after the Airport, the next stop is Hell.
I didn't get out of the train; the doors opened, and I just pointed my camera and clicked. In fact, I was hoping to come back to Hell on another day to have a proper look around. But I didn't get the chance.
The word "Hell" obviously means something in the Norwegian language. But I can always say, if anybody ever tells me to go to Hell, that I've already been there!
