Conceding to the holiday spirit, Count Dracula bares his fangs in a ghoulish grin as he watches Reva Boren make a bloody Halloween investment Thursday at LDS Hospital. The visit by the caped and winged figure, a red-blooded kind of vampire, is part of a statewide drive sponsored by IHC Blood Services. Officials say there's a critical demand for blood donors from November through January. To meet the needs of Utah patients, more than 288 pints of blood must be collected every day - about 75,000 pints per year. And blood has a storage life of just about one month, IHC officials say. For more information, potential donors can call 321-LIFE (321-5433).
