For Karis Tsolomitis, 17, next week’s World Youth Day in Australia will bring to an end three years of anticipation. The Bainbridge, Wash., resident has been looking forward to the trip down under ever since her older brother returned from the 2005 World Youth Day in Germany with pictures and stories in tow. “I actually started saving for it when my brother got back from his trip. I was like, `I’m so going there,”‘ Tsolomitis said. “It’s really changed his life a lot, so we’ll see.” Tsolomitis and approximately 15,000 other youths from across the U.S. will attend the six-day festival, which begins July 15 in Sydney. Pope Benedict XVI will conduct mass on the final day of the festival, which organizers expect to draw as many as 500,000 people.
