I have liked every one of the billboard designs developed by the FFRF and hope I will live long enough to see one here in Mississippi. Having said that, I'm not particularly crazy about their most recent billboard design.
My initial reaction was something like, "Oh great, now the Christians are going to accuse us of being hedonists." Of course, this is silly because we are already accused of this. I like the "enjoy life now" message, even if I question what it has to do with freeing oneself from religion. I think it is the "there is no afterlife" part I could do without. When trying to reach the religious, this seems like a better message to impart down the road after there has been some initial dialogue.
Of course, I'd still love to see one of these on my daily commute. It wouldn't be my first choice, but it would be a hell of a lot better that the AFA.net billboards I have to look at now!
