Well, you never know. I scan in everything I can get my hands on. I came into some slides made by my aunt and uncle when they were stationed in Japan. They were involved in writing the new Japanese constitution at McArthur's headquarters. They look like beauty shots. Buildings, etc. But looking closely you can see these are War Ministry Apartments. They spent years there. Sometimes you don't know the value of a photo until years..maybe generations later. So I say scan scan scan. Storage is getting cheaper all the time. And flipping through photos on line is more pleasant than holding a photo in your hand and degrading it. Photos fade. Digital scans don't.
