What do you do with postcards you bring home?

Well aware of my limitations as a scenic photographer, I often buy particularly nice postcards to bring home with me. I sometimes also buy more than that and despite my intentions, never get them sent to anyone. I've even mailed a few to myself from foreign parts, which seemed a little strange but was kind of fun when I picked up my mail after I got home. So. The real reason for this posting: there's a kid in Colorado who's going blind. His mom had the brilliant idea of having people send him postcards so he can literally see the world while he can. He has some kind of special visual memory that will allow him to keep those pictures in his mind for years.

In case anyone's been doing some New Year's housecleaning and may have some extra postcards from farway places - or even their own home town or state - that they don't know what to do with. Happy travels, everybody!
