Backpacking is like driving a car, although much safer. It's very easy. Mostly common sense. If you completely mess-up, or get very unlucky, problems are possible.

On Saturday, I passed an unusually grim accident scene in Pennsylvania, & mostly succeeded in not looking.

What caused the accident? I certainly don't know, and I don't care to know whether somebody in particular was to blame.

Just an unusually bad scene, and obsessing over it isn't useful.

When I used to work for a small newspaper, the editor would always get photos of smashed-up cars and put them on the front page. Perhaps he felt it was in the public interest as a means of educating drivers.
