I'd like to comment on the "rules" discussion of a few days ago. Disapproval of Google Earth (GE) images can be understandable on the basis that it might allow anyone to post images of obscure airports to which the poster had never been. I suspect such posters would be quickly unveiled. And, on the other hand, how many in this thread have actually taken photographs of every airport they've ever been through? Some of the most interesting challenges in the last few months have been GE images, with accompanying cryptic clues.
Is there not some middle ground? E.g. airports we've been to/through/overflown?
