This does not constitute legal advice. There does not appear to be a federally registered trademark for "Akston Vineyards." To be safe, make clear there is no affiliation between your website and Atlas Shrugged Movies nor Ayn Rand or ARI. However, you can say you are a huge fan of the book and/or the movies and my choice of this name is to express admiration for Rand and to encourage people to read the book and see the movies. Or whatever you'd want to add.

Whether you make money or not is irrelevant. The Ayn Rand Institute has pursued people who attempted to market their own tie-in products such as Rearden Steel trucker's caps on Cafe Press. However, if you put the name Akston in a search engine, I think that you will be pleasantly surprised at the irony.

You might want to take a close look at some of the handles of the contributors to the Gulch. By the way, that certainly seems like a dream "retirement." Good luck.
