To many people in Iowa, David Twombley and Larry Hoch are a symbol of marriage.
But a decade ago, when the couple met, neither really considered marriage a possibility, let alone imagining they would be thanked over and over for helping others marry.
"My parents had a wonderful marriage and my brother had a wonderful marriage, and I was naive enough to think everyone had a wonderful marriage," says David. "And it was something I never thought I'd have."
