Thanks for chiming in! Non-electronic and secure are going to be interesting things to consider, especially in combination.
Bank safe isnt totally out of the question but I would like to avoid them if I can. Second location wouldnt be impossible but offline doesnt mix in well with that since my family is a mess.
If one was to make a hobby out of this I can imagine peeps putting their secrets in plain sight but make them uninteresting for the uninitiated.
