I stumbled upon this when I was rummaging through some of my things.  It’s a waiver for visiting the Demilitarized Zone on the border of North and South Korea.  It pretty much says that my safety is not guaranteed if the North decides to attack.

The United Nations Command, the United States of America, and the Republic of Korea cannot guarantee the safety of visitors and may not be held accountable in the event of a hostile enemy act.

There’s even a section about not interacting with the soldiers on the other side too.

Fraternization, including speaking, making gestures or associating with personnel from the Korea People’s Army/Chinese People’s Volunteers (KPA/CPV) side, is strictly prohibited

Anyway, the full text is here for people who are curious
