Called up PDN just now. They said there are a few places organizing blood donation drives. Stadium Bukit Jalil (Sat and Sun), somewhere in Jln Pudu which I didn't ask in detail as I won't be heading anywhere near there. The one I'm interested would be in Kajang, which would be held in Metro Point Kajang (Opposite Kajang Hospital). It would be on 3rd August 2008, on the first floor.
