If you're a PDX local (perhaps even one of our recent Portland DASH participants?) and would like to hear more about puzzle hunts, feel free to visit the site and send a comment to the organizers--or submit a proposal of your own! Deadline is October 4th.
They'll be selecting talks sometime next month, I think. If they pick me, I hope to present something half as interesting as my friend Jeff's "IT in Africa" talk (O'Reilly Ignite UK North, 22 Jan 2009).
