>>>Snail mail would still be the best way to speak unobserved.

Nope. Fax!

[Quix]

I don't think there are many ways left to communicate unobserved.

FAX is CERTAINLY ****NOT**** IT.

SNAIL MAIL was not it as long as 30 years ago when we reportedly had machines which read mail automatically without opening it.

Nothing that goes electronically is that secure though very, very, very robust encryption with very long keys MIGHT be secure.

Perhaps standing in the forest near a waterfall with a fairly loud boombox with random noise pouring forth. . . whispering to each other . . . might work.
