Hi, Bill! Yes, it's pretty straightforward. Everybody signs up and the coordinator compiles the list and sends it via email to everyone on it. The only condition is that it must be a lighthouse card; it can be a real one or a fantasy one. Many of us make up our own cards using photos of lights we have photographed. Last year, we decided to extend the number to 30, so let's try to do that. It's up to the members to sign up - the more the merrier!
