The Rock-n-Roll Up Your Sleeve Winter Blood Drive encourages donors of all blood types to donate. Leticia Mondragon with the Coastal Bend Blood Center joins First Edition to preview tomorrow's event.

Blood is typically in short supply this time of year because of the holidays and travel schedules.

Four mobile blood banks will be on hand in the parking lot in front of Cavender's Boot City. The event will be held from 10:00 a.m. To 7:00 p.m. Donors will get a long sleeve t-shirt, Sonic coupon, and pint of ice cream from Blue Bell.
