I had a friend growing up who battled cancer. Somebody choosing to give blood is what saved her when she needed it the most. She had a rare blood type, but they were able to match it because somebody chose to give blood!
Challenge your friends (or anyone for that matter) to a friendly competition! Who will win the battle to do the most social good for your community?
Put your virtual blood drive campaign against one or even multiple other campaigns to see who can recruit more blood donors for the American Red Cross.
