CHICAGO—In what many were calling "the best Father's Day present ever," the nation's dads were treated to a Mark Knopfler meet-and-greet Thursday, spending several minutes chatting and posing for photos with the former Dire Straits frontman. "Wow, I can't believe I got to meet Mark Knopfler," said Paul Miller, 45, a father of three from Omaha, NE. "I love that song 'Walk Of Life.'" According to the nation's dads, Money For Nothing is their favorite Dire Straits album.
