As you may know the Robert Heinlein Blood Drive at Dragon Con is one of the largest (if not the largest) blood drive in the USA. It is held in honor of The great SciFi author Robert Heinlein, who started the tradition of blood drives at SciFi conventions in 1976 while the GOH at World Con. The last three years we have had at the DragonCon Robert Heinlein close to 4000 potential donors donate between 9,000 and 10,000 total component units of blood each year (each donation is broken down into three component units). To make this successful we need lots of volunteers to encourage people to donate, welcome them, give out snacks and gifts after the donation and just be ambassador to everyone. The commitment is small and the reward is great. To help go the link below and join the Blood Drive volunteer group to be updated on when and how to volunteer.
