There seems to be an annual tradition of people posting photos from Pittsburgh's airport of the shitty "Allegheny County Welcomes..." LED message sign above some escalators displaying "WELCOME ANTHROCON". This is something the Convention and Visitors Bureau does without the con getting involved.
Further Confusion has decided they need to one-up that, and went and got an outright advertisement put up in the San Jose airport.
Presumably the advertisement is meant to attract people who have for years had the urge to dress up like a dog but for some reason remained blissfully ignorant of the existence of the Furry Fandom. "Sorry, Dear. I need to go back to San Jose next month. There was a picture of a dog costume on the screen and I absolutely must attend this event!"
