Darkstar is the Science Fiction and Gaming club at the University of California at San Diego. It has been around since December of 1978, and has had many fine adventures in the intervening years. Salient features of the club include: a 4000 book library of Science Fiction accessable to anyone with an ID card of any sort (No need for university affiliation), dinner each Thursday night at a different restaurant within the San Diego area, gaming meetings on alternating Saturdays, and above all a penchant for mischief.
(Have you ever seen a trebuchet constructed out of forks using a sugar dish from Coco's as the counterweight?)
