In the process, I have found a great many things. I have found the Wolfman/Perez Teen Titans graphic novel, "Games", which I bought many years ago, misfiled, and never read. (I have now started reading it.) I found my father's typhoon journals. I found two copies of the same Crosby, Stills, and Nash songbook.
I have found a huge stack of comics semi-pro zines such as Alter Ego and Backissue which I have never gotten around to reading. I am out of magazine-sized boxes. *sigh*
And photographs. I have found photographs, including a color laser-printed image of my mom and dad holding one of my nieces and nephews as a tiny baby. All of those nieces and nephews are in or through with college at this point.
More stuff for recycling too, mostly old convention program books and manuals for equipment that we no longer own. ("Oh, look! That garage opener broke down five years ago.")
On the other hand, the manual for our Sleep Number bed may come in handy when we move it tomorrow...
