AUBURN – As the local blood supply is at critically low levels, the American Red Cross and WBLM will host their 10th annual “Out for Blood Tour” to boost inventory.

The “blood tour” kicks off at 6 a.m. on Thursday morning at the American Red Cross Donor Center at 524 Forest Ave. in Portland with a pancake breakfast. The Portland center will be open until 1 p.m.

The tour moves to Auburn and Saco with WBLM listeners competing for bragging rights for most donors at each blood drive. The Auburn Mall location has traditionally had the most donors, while the Saco United Baptist Church hopes to earn bragging rights this year. The Auburn and Saco drives are open for donations from 11 a.m. to 6 p.m.

Donors will receive a Red Sox Nation Blood Donor T-shirt and can enter to win a pair of Red Sox tickets for the Aug. 1 Red Sox/Oakland game at Fenway Park. Donors at the three tour locations will be eligible for the “Blood Donor of the Game” prize. The Red Cross is urging eligible donors in Maine to give blood to boost a low supply severely impacted by the Fourth of July.
