CLEVELAND -- A billboard campaign that features atheists, agnostics and other non-theists sharing messages about their views started recently in northeastern Ohio.

Participants in the campaign sponsored by the Wisconsin-based Freedom From Religion Foundation and its Northern Ohio Freethought Society chapter say one goal is to let area non-theists know others share their views and make religious believers more comfortable with them.

A Richmond Heights couple and a University of Akron student are among Ohio residents appearing on some of the 11 billboards in areas including Cleveland and Akron.

The Wisconsin-based foundation is a church-state watchdog organization that claims more than 20,000 members, including about 550 in Ohio.

The organization debuted its "Out of the Closet" campaign in Madison in 2010 and has taken it to other U.S. cities.
