WorldCon chose not to sponsor a blood drive this year. For the convenience of those expecting to Pay It Forward by donating blood The Heinlein Society and Virgin Hotels, a block away from the Hyatt, will have a blood drive on Sunday. Schedule your appointment early as the drive is open to the public before WorldCon starts. More information will be available as well as a free book with a cool bookmark at The Heinlein Society Fan Table at WorldCon.
