Crazed ramblings is a paper note in Fallout 76.
The note can be found during a random encounter, on the corpse of an escaped inmate.
They're poisoning the water! It's making everyone green. Why are they green?! Huntersville, go, see for yourself. I'm not crazy, they're crazy, I know what I saw. They lock me up, make me take pills. They'll see. They can't keep me in here!
