Flash Drives
I cannot say enough good things about them. Prism99 was asking about preserving pictures in another post.
I have several with music, videos, the Bible, (all of it), my mother's genealogy, my father's diaries from Pearl Harbor, greeting cards I've shared with Jim, birth certificates, tax records, and quite a few other things. I also have one devoted entirely to my quilting stuff. If you live in an area where you have the occasional tornado, wild fire, or earthquake, it may be a very good idea to have all this information on a flash drive in your purse at all times.
