I've been meaning to remind you all for awhile, but if you are anywhere near-ish to Seattle you should really consider checking out Emerald City Comicon. This year's Comicon is March 1st through the 3rd.
This is one of my favorite events of the year. We've gone every year since its inception and it's bigger and better every time. It's really become a pop-culture convention, much like San Diego, but thanks to it's smaller size and scope is still very doable for families.
Tickets can be purchased here: http://www.emeraldcitycomicon.com/tickets/ or at many local comic shops, including my favorite: Arcane Comics and More.
