Non-stop gaming from Friday through Sunday!
OwlCon is a great little local convention. Pre-registration closes on Friday, February 8, and costs $25 or $18 for one day pass.
Many RPGs, Board / Card games, Miniatures and all the regular con stuff. See event listing. Held on the campus of Rice University in the Student Center.
If you've never been to a Game Convention I recommend OwlCon. It is a (relatively) close and good opportunity to check one out.
