Preparations are underway for a big birthday celebration this week.  Packy the elephant turns 49 at the Oregon Zoo. Visitors will get to share in some birthday cake, games and crafts.  There will also be a drawing for kids to get a chance to deliver some cake to Packy. "Elephantastic" is scheduled for Saturday from 10 a.m. to 4 p.m. Packy is one of the oldest Asian elephants in the U.S.
