As blood supplies continue to be below normal, East Texans are called on to help. Carter blood care held a 12 hour blood donation marathon in Lufkin today. The group tied the event in with Texas' independence day. Organizers say today was a great day to donate blood and help save a life on a day when Texans remember those who gave their lives to make this state a better place to live. But the center wants everyone to remember they need blood donations every day.
