"What, you've never had a basement flood?"
A couple times, however the negatives were high enough off the ground in a nice cabinet. I even have my father's negatives from the 30s-80s. I guess there's a part of me that misses that, I still have every negative / slide from every photo I have ever taken and not one has ever become corrupted or gone bad. I don't need 2-3 backups, though I have scanned most of them into my computer. Label the negatives, put them away and one could forget about them, today we have to remember to back up and make a back up of the back up and then we can't forget about the files because media goes bad, so we need to keep moving the files from drive to drive............................and so on and so forth.
