GEEX (Gaming & Electronics EXpo) is July 16th and 17th in Utah!
This is a huuge convention. I know the guy who's leading the committee, and he is putting me in a position to speak on one of the floors about Indie Game Development.
It's pretty much the only choice for folks in or around Utah for a gamer convention. I believe they told me the first one, held 2 years ago, had 16,000 attendees. Be sure to check it out!
