Several large billboards around Baltimore welcome atheists and agnostics, directing them to the Web site of the Baltimore Coalition of Reason.
The signs are part of a national campaign funded by an anonymous Philadelphia businessman, The Baltimore Sun reports. The American Humanist Association has also greeted the Christmas season this year with ads on the sides of buses in Washington and several other cities that say it is possible to be "good for goodness' sake" and not for fear of divine punishment.
Teresa Cherry, a student at the Community College of Baltimore County, said she was excited to see a billboard over Interstate 95. The headline read: "Are you good without God? Millions are."
"My friend and I were just discussing a few days ago whether or not there was a community of others like us in Baltimore," she said.
Local and national coordinators say the goal of the ad campaign is to overcome negative stereotypes of non-believers and to create a free-thinking community.
