If there’s anything Patrick McCaffery has known and enjoyed in his short life, it’s Legos. He has a 5-gallon bucket nearly full of the plastic blocks stashed away at home. “My dad introduced me to Legos at a very young age,” said McCaffery, a 10-year-old Regina Elementary fifth-grader. “They’re just really fun. When I grow up, I want to be a game designer or a toy designer.” Patrick now shares his love of Legos with 11 of his classmates in the Regina Lego club. Since mid-September, the group of fourth-, fifth- and sixth-graders has met twice a week for two hours to train for the 2003 US FIRST Lego League Challenge.
