Me.. wow, I am one paranoid son of a bitch!
Usually, I type mine into Word/Pages (I have a Mac). Just incase anybody would find them, I save them on my flash drive, which has another seperate volume INSIDE a seperate volume (.sparsebundles), which are encrpyed with a 256-Bit Code. Only I know the password so... It's a very slim chance that any would find them.
Yes, I am paranoid, if I already answered that question.
