The Heinlein Society and Arisia are once again running the Blood Drive; last year we raised 120 pints of much-needed blood. Look for the table in the lobby next to the Info Desk or watch for our folks out with clipboards.
Note that 16 year-olds CAN donate by getting a form filled out by their parents.
Please see http://2013.arisia.org/blooddrive for more details and links to eligibility criteria and forms.
