I've been donating blood with the red cross for at least a decade now and have never had any bad experiences. When I got to college and joined a service sorority, they were one of the national partners and we set up drives with them. So many people always come out to donate blood and money.
Worked with Wounded Warrior during my time with the Student Veterans Association in college and again at my internship at a pr firm that handled some of their work. Each year when a rep comes to town to spread awareness during the festivals, they inspire and help sp many!
