I want to second Rich--the Wisconsin Unit is a great one, with a strong vintage presence. Check out our web site at
WBCCI Wisconsin - Region 7, Unit 116
The Wisconsin Unit spring rally is coming up May 16 - 18. It will be only about 60 miles up the road from you in Jefferson, WI. This will be a "buddy rally", so you are welcome to attend even if you're not a WBCCI member. See details in the latest Badger Bulletin, on the web site. If you want to attend as a non-member, PM me and I will sponsor you.
If your Airstream isn't ready to take on the road yet, you still might want to come up Saturday and meet the folks. The Open House will be 3 - 5 PM so you can tour everybody's trailers.
If you can come to the rally, a guarantee and a prediction:
I guarantee you'll be welcome.
And I predict you'll join the Wisconsin Unit!
See you up the road,
