So... Yes, Erin, you are correct! Deanna Raybourn is indeed our mystery guest! Yay! Deanna has graciously agreed to play 20 Questions with us and will drop by to check out any comments left for her.
Claire, Jen, Rachel and I are supremely excited to have her here and cannot wait for tomorrow.
As for the contest, all who commented are in the hat to win and we'll announce the winner tomorrow. :) Good luck, and hope to see you all there!
