The NYT has a treacly story about airport chaplains. It's not worth reading but I loved one line. You'll know it when you see it:
"We sometimes have to reach out to people who have no idea we exist," says the Rev. Chris Piasta, a Catholic priest at JFK's Our Lady of the Skies Chapel, home to a statue of Mary standing on a propeller.
Admit it: you love knowing about propeller Mary.
