Have You Made the Evidence More Permanent?

A friend and I were joking around on Facebook about using tire tracks in the snow as permanent evidence of something and it got me to thinking.

Have I converted all my "evidence" into a more permanent format? While I obviously don't have my information in the snow, some of it is stored in just as fragile of a way. Memories that are only in my head, photographs I have the only copy of, research conclusions that I've not written up. They could all easily be gone in a moment.

When the snow melts, those tire tracks are gone--and so is the evidence that a vehicle passed through.

Are there things you need to preserve before the sun comes out?
