Different idea from the posts so far.
Contact a local school and offer to show youngsters the wonders of silver-based photography by doing photograms with them. Who knows, they might get into the hobby, become APUG members some day, and make sure Kodak and Ilford keep making the stuff for all of us.
Just a thought, but to little is done to get young people interested in what we do and love, and fogged paper may serve a useful purpose this way.
