Congratulations on your new Airstream. There is a major Airstream rally occurring in North Carolina October 25-28 at Tom Johnson Camping Center in Marion, NC near Asheville. About 250 Airstreams are signed up for the event where you will have the opportunity to meet other Airstreamers from the Carolinas and neighboring states. All Airstreamer's are welcome, you don't have to be a member of the WBCCI (Airstream Club).
Check out the Alumalina 2018 thread on Airforums for more details on the rally and to sign up if you can make it.
Here's a link to a video from a previous Alumalina at another location in South Carolina. It will give you a feel for the camaraderie and activities at an Airstream rally.
