Tickets for the big game are going online for as much as $4,000, but for a father and daughter from Centereach, the tickets were free and the trip priceless.For Jimmy Oliveira and his 8-year-old daughter, Gina, every Sunday is game day. The tradition of watching football and rooting for the Giants is so special to the two that Gina Oliveira entered their story in a Super Bowl contest on the website Fathers.com, and won."When I found out, I just lost it," Jimmy Oliveira says, "and the first thing I thought, it was, 'I have to tell her.'" The Oliveiras drove through the night in their RV filled with Giants memorabilia and arrived in Indianapolis, Ind. this morning to get their prize: tickets for two seats four rows away from the field.
