Science Fiction Convention with Fantasy programming

We like to think of MarsCon as a weekend long party for people who enjoy Science Fiction and Fantasy. It's a chance to gather with 1,400 or so of your closest friends (or make new friends if you don't know all 1,400 of us), and talk about science fiction, fantasy, cosplay, gaming, your favorite author, or whatever else you like to talk about.
