A few weeks ago Anthony Ketchum, one of the For Our Grandchildren founders, received a handful of mysterious postcards in the mail. The postmarks that I can read indicate that they come from around the USA, and were sent at the beginning of May. They express words of encouragement and thanks written very neatly and signed with only a first name; they all show evidence of being the work of the Postcard Underground. One of them is drawn by hand with a special message related to our work.
A search on Google shows indications that the Postcard Underground has contacted other web sites with a mission similar to ours.
