When my daughter lived in Belgium and I went to visit her in October 2006, I took about 200 keys with me and met with Michael at the train station in Brussels and he had as many foreign keys for me - that's when I got started collecting foreign keys. Michael and I have made 3 or 4 trades each year since then. Ken Stryker is the person who aided in my introduction to Michael. Small world.
