Center offers blood donors free tickets to Cincinnati Zoo

CINCINNATI (AP) — A blood center in Ohio says anyone who donates blood over a period of several days will receive a free ticket to the Cincinnati Zoo.

Officials with the Hoxworth Blood Center in Cincinnati said the offer applies to those who donate blood or platelets to the center today through Friday.

Center officials said blood donations tend to fall as temperatures rise and blood usage increases, and that can result in lower blood supplies.

A center spokeswoman said Hoxworth already has experienced a number of blood shortages this summer.

Hoxworth operates several donation sites.
