The alumni list at Lewis and Clark High is a jaw-dropper: politicians, military heroes, opera stars, actors, even a Nobel Prize winner. And athletes, dozens of them from every decade and every sport, their character built, Bob Lobdell believes, on the bricks laid 100 years ago and the wisdom of its teachers and staff. “At LC, we walk in the halls of history like no other school, the same halls as the great scientists and athletes,” said Lobdell, a former student, teacher and coach at LC who this weekend will preside over a reunion like no other.
