Friends of mine are at one of the biggest conventions at San Diego at present. With 130,000+ in attendance each year for the last few years, we're really in a golden age of geeking around the world at present. I read that the 4 day convention is expected to net about $180million in economic impact in the city alone. Not surprising since there are heaps of advance and convention only collectibles on offer. Here's some of the photo's from the sneak peeks of the convention.
