Every Feb for the past few years I've been going to a great convention, the East Coast Ground Zero Games Convention.
Its a small con dedicated to sci-fi gaming. The crowd is very friendly and the gaming is fun and varied. I usually run one or two game each con. this year I'm going to run two, a Stargrunt game and a Tomorrow's War (Ambush Alley) game.
If you are in the Southern NY are in Feb I highly recommend checking it out. The next con, GZG ECC XV is scheduled for February 24-26,2012, at the Owego Treadway Inn in Owego, NY.
The web-site to check for more information is: gzgecc/gzgecc15/ (http://www.warpfish.com/gzgecc/gzgecc15/index.shtml)
The photo-reports of past events are fun to go through.
