Puzzle event incoming!

Google and Virgin Airways present Day In The Cloud. Coming June 24th.

(At least, I think it’s puzzle-related. The front page says “scavenger hunt,” which is one of those phrases that makes me hiss like a vampire faced with a cross, but the site also promises “brain-busting questions.” We are also informed that “puzzle people outside the United States are welcome to play,” which makes it sound like this is an event for puzzle people, doesn’t it? Anyway, I’ve signed up.)
