A pair of Iowa-based groups aimed at reaching out to atheists, agnostics and nontheistic people have announced their formal launch with four billboards, two of them in the Quad-Cities, that proclaim: "Godless? So are we!"

The groups, the Central Iowa Coalition of Reason and the Eastern Iowa Coalition of Reason, represent an alliance of 13 nontheistic groups in the state, including Secular Humanists of the Greater Quad-Cities Area, organizers say.

"The stated and sole purpose is to make any atheist, agnostic or non-religious people in the area aware that there are groups of like-minded people who have been around for a long time," said Peter Nothnagle of Iowa City, a representative of the Eastern Iowa Coalition of Reason.

The billboards in the Quad-Cities are at 60th Street and Welcome Way in Davenport and at John Deere Road near Interstate 74 in Moline. They will be up for four weeks, organizers say.

The other two billboards, with one up already and another on the way, are in Des Moines.

The Washington, D.C.-based United Coalition of Reason provided $10,000 in funding for the billboards.
