Not to rehash this old wound too much, but I too have NO intetention of renewing my membership after the free one runs out.......
I mean the newsletters practically have people with oxygen masks throughout the newsletters I receive. Plus I am with Steph...the clubs are not designed for the average working folks out there. Add to the fact the high costs of these trips (and inconv dates), make it a dead club in my book.
I too love the tight knit Airstream Community like the next person, however, the group as I see it is mostly there for retired folks who have the time to do these things and that is wonderful for them. However, there are a good number of we 30 somethings (can't believe I'm actually a 30 something...

) that can afford to be into Airstreaming, but have no real group connections to be able to go on rallies or care to pay the cash for the memberships and then these fairly high sums of money to go camping. Speaking for myself in particular, the informal stuff that has been done here is really a hit for me because the group here is in touch with each other and has a good connection with the realities of non-retired life.
I too belong to a car club and I have to say because it's membership is diverse, it is able to meet everyone's needs at some point with the multiple offerings it has. Costs are low as are flexible dates and times that are in tune with both the retirees and the working folks.
BTW, the comment about the oxygen masks was a bit of an exaggeration....if I were in my 80s, I'd think it was attractive...
(Jumping off my soapbox now).
