There is a facebook group, but joining that does not join you into the SOS club. Visit
South of Sixty Club - Home for membership and other information. My wife and I found the facebook group last summer and then officially joined when we arrived here in April. We have been to a couple of meetings/events. Nice people and fun. There are some singles as well if that's of interest to you. You can PM me of you have other questions about it. Dues are 10 whole dollars per person per year.
