The American Red Cross is hoping people will come out this weekend to help fill the local blood bank – and in return, fill up their own gas tank.Organizers are putting on the 5th annual Chill and Fill event on Saturday, February 23rd.It’s at the Spectacular Event Center on Griffin Road from 9 a.m. to 2 p.m. Donors will be eligible to win gas cards, t-shirts, even a home heating fuel package. They hope to have at least 150 people give the gift of life.Peter Morrison, with the American Red Cross, says, “Right now the blood supply is adequate. But day to day we have to collect 300 units of blood because every two seconds, somebody needs some. So it’s a constant challenge for us.”You can save yourself some time by making an appointment to donate. Just call 1-800-RED-CROSS or visit www.redcrossblood.org.
