The strangely compelling (or is that compellingly strange?) Curt Harpold will be familiar to anyone who has attended more than a few science fiction conventions over the past 30 years. He's a magician, M.C., auctioneer, folk/filk singer, concertina player, SCUBA instructor, computer geek, and all around good guy. Curt returns to MarsCon this year for the Charity Auction, Saturday night entertainment, and various panel discussions.
