I'm involved with literary and other groups that host similar events -- one in particular does a party on the author of interest's birthday. The difference there is they only bring books to display, which the neighbors don't really see. I don't see this as all that different -- it doesn't have the air of "flagrant display of wealth" -- many of the cars are older Rolls, and not extravagently expensive compared, to, say a 500- series Mercedes. The pictures we put up on the web of our event are for members who couldn't attend, mainly, and for the attendees to show to their friends and such. They really don't look snooty, and it doesn't seem all that snooty affair, with the metal chairs and no catering staff. ~ Huntsman
