DEFCON and Blackhat are basically events where everybody wears signs on their back that say "Kick me!" - the main point of the conferences are attending talks about surprising ways of kicking people, but there is a lot of fun to be had in avoiding getting kicked too.
@jpf Going to those types of events are just as bad as people bitching about biometrics on their YouTube videos. The sign you're wearing on your back is "I know too much, so flag me guy walking around and pretending to be a nerd." I definitely wouldn't go home with any of the prizes. You know there's facial recognition cameras too and it wouldn't surprise me at all if they drive around and scan license plates like they've been caught doing at gun shows.
