The Freedom From Religion Foundation just put up this “Imagine No Religion” billboard in Terre Haute, Indiana (courtesy of a donor who wished to remain anonymous):

“There are many nonbelievers in America, including in Indiana, and we want them to know they are not alone. We’d also like to invite believers to imagine a world free from religious wars, sectarian strife and superstition,” said Dan Barker, FFRF co-president.
“Like John Lennon, I’ve found that nature and reality are enough for me. I, too, like to imagine no religion, no hell below us, above us only sky. The only afterlife that should concern us is a secure and pleasant future for our descendants,” said Annie Laurie Gaylor, FFRF co-president.
It’s been about two years since FFRF put up a billboard (with the same design) in Indiana.
