At that time, there was only a 3-day supply at area hospitals.
Rain, snow, and bitter cold have kept many donors from coming out.
However, that didn't stop first responders today in Pennsauken, New Jersey.
Police, firefighters, and emergency medical services members competed in the first-ever Battle of the Badges blood drive.
They all tried to see who could recruit the most eligible blood donors.
The drive continues till 8 tonight.
