Astronomy (I've been with the Planetary Society for 18 years), I also love movies and science fiction in general (in all forms; books, movies and TV shows). I'm also a huge fan of the rebooted Battlestar Galactica, Dr. Who (old/new), as well as the 1960s shows The Prisoner and Twilight Zone. New favorites include Breaking Bad, The Walking Dead and Mad Men.
Got a hotel for San Diego Comic Con by the skin of our teeth. It was REALLY tough this year, even with my wife's pro registration. We're kind of far from the convention center this time, but at least we're on the shuttle route, so...yay for that.
