Many churches in the area do Angel Trees, where a tree is put up with ornaments on it with the name of a child who has a parent or parents who are incarcerated on it. You select a child and send them a gift "from the parent" who is in prison. If you really want to get more personal with things, or just donate in a different way, I think going to a local church and selecting some kids off the Angel Tree would be a great way to get those trains out.
