Thanks for the reply - no problems with that at all, Al. Invited guests, spouses, etc. would not be a problem, but we would prefer registered members over unregistered people, given potential logistical issues. There are a number of guests who will be invited who may or may not be HFC members at this point, however. People who are not welcome here as members (for causing problems, etc.) would also not be welcome at that event, that's all. It is planned as a positive, fun experience, and there is no reason to potentially ruin that.
