This is the response I got from JeepRecoveryTeam on the Pirate board, when I asked where I needed to be to hear my ticket called.

Seriously, we build a database comprising of all the electronic tickets and paper tickets. And do a double blind random pick. From there we back out and determine your contact info and call you up (that's the coolest call ever).
There winner will then have ample notice to get to the Jambo where we call you up on stage and people throw things at you
