He was in Portland a month and a half ago, for the WDS.
Come attend Camp Mustache near Seattle next Memorial Day, if you'd like to meet him. Great guy to hang out with. :)
And he always does a big free public meetup at Gasworks park the night before CM starts (at least he has the last 3 years), so you can attend that if you just want a selfie, rather than to hang out with him all weekend.
