Note: Denver Comic Con has provided my family with passes and Grayson's photo but words are mine.There has been a real shift in our family entertainment this year. It's not just us telling Dex about cool stuff coming to town, he is noticing it happening around him and requesting to go. Case in point is Denver Comic Con, which runs June 13-15 at the Denver Convention Center. Of course I have heard of it before. Let's face it, we're nerds (and proud of it). The timing just never worked out. But when your graphic-novel loving, Dr. Who-vian, Minecraft-obsessed kid asks about Comic Con, you put it on the calendar.
