I just got back and found an email from TigerHawk
Do you live in the Princeton, New Jersey area? If so, please consider going by Princeton hospital and donating blood. Our HR department got a call requesting help. Apparently there is a particular need for B+ blood (about 8.5% of you), so if that is your type please make a special effort to donate tomorrow. The hours are 7:30 a.m. – 3 p.m., and the details are here, or call 609-497-4366 for more information.
(No, not Princeton-Plainsboro Hospital.)
