sorting through pictures

Today I started one of my last "sorting" projects before my move. Pictures, many many pictures, two big deep drawers full of snapshots.  Some pictures are easy to keep - old pictures of parents and grandparents, pictures of grandkids, pictures of friends.  Some are easy to get rid of - unidentified scenic views, blurry unidentified scenic views, mystery people.  Some I can give away like packets of pictures that belong to my daughter.  Why are they in the drawer?  But some are a bit more problematic. I'm not keeping pictures of my ex children-in-law but what about a picture of my daughter in her wedding dress from that first ill fated marriage?  I guess if it was easy I would have done this long ago.  My plan is to save the best family pictures, arrange them chronologically, and have my son copy them onto a cd or whatever electronic device he recommends so I can hand on to my kids one little cd or memory stick of pictures which they can then tuck away in a drawer until they start sorting stuff out.
