David Calvillo used to think praying the rosary was for "old ladies and funerals."
Then he went to a Catholic men's retreat in 2008, where for the first time he felt the rosary's spiritual power as he prayed it with 79 other men.
Calvillo, 49, is now on a crusade to convince Catholics that "real men pray the rosary," the name he gave a nonprofit he founded last year.
