I mentioned earlier that I’ll be presenting twice at the Arizona Family Expo in Mesa on January 21-22, 2011.

As a blogger of honor at the Expo, on 28 December 2010 I will be giving away two tickets for free registration. To enter, send me an email at the contact page with “Arizona Expo” in the subject line and tell me what your biggest research challenge is at the moment. Things are crazy busy this time of year, so I’m giving you a week to get your entry in. (And please enter the contest just once.)

You can enter now through 11:59 PM PST on Monday, 27 Dec 2010. Emails will be numbered in the order in which they land in my inbox. On Tuesday, 28 December, I will randomly draw two numbers and announce the winners.

Looking forward to meeting the winners in Mesa!
