Hey Ken - it is a GREAT trip. The AGLCA is the primary group to belong to. It has been 8 years since I have been a member and it switched many years ago from volunteer to a commercial group. They have Rendezvous at a couple of ports along the way and it is a week of gathering with other Loopers. Order the AGLCA burgee and fly it now - anyone who has done the loop will stop to talk and advise.
My wife of fifty years, Audine, passed away last Saturday from ALS and I am a bit overwhelmed right now, but will try to get more info to you later.
