Any blood donation is welcome, but those who have types O-negative, B-negative, and A-negative are needed the most.
Officials say with more people out and about in the Summer, supplies can run dangerously low. That's why it's hosting three major blood drives over the next few months.
"When folks are traveling, that could create an opportunity of shortage," said Red Cross CEO Amy Canterbury. "We don't have a lot of folks giving, and you know there's a short shelf life on blood. 42 days is as long as blood can be used and only five days for platelets, so that's why we always have a constant need for blood and make sure there's enough to make our commitments to the hospitals we have contracts with."
Today, the Red Cross hosted a different kind of fundraiser. This one was to collect school supplies for kids whose parents serve in the military. Evansville Otters baseball players were there to meet fans and give free tickets to tonight's game to those who made donations.
