Greg Belfrage interviewed Bridget Devlin and Luke Smidt, and Ken Versteeg about the Heroes Behind the Badges Blood Drive in Sioux Falls, SD. This is a friendly competition between the fire department and the police department to see who can rally the community the most to give blood.  The blood donations will go to directly support critically ill patients in the Sioux Falls area. You can go to cbblifeblood.org to pick a time and a location to give blood this holiday season.
