Right this minute, Ernest is completing his 500th hour volunteering at the zoo. He is a C-I-T for Zoo Camp this week. He's been working hard to accumulate 500 hours by the end of the year -- the reward is a 50 year membership to the zoo. (Starting in 2010, 2000 hours will be required!)
Meanwhile, kids from his school have to do 20 hours of community service in order to go on the 8th grade trip. He's happy that he has more than fulfilled that requirement!
