The billboard, which according to Mashable was paid for by the LGBT advocacy group Planting Peace, reads:
"Dear Kim Davis, the Fact that you can't sell your daughter for three goats and a cow means we've already redefined marriage."
Davis, a county clerk in Kentucky, was released from jail last week after a judge sent her there for refusing to issue marriage licenses to gay couples due to her religious views.
That, of course, made her an instant hero for GOP candidate Mike "God Already Solved Racism" Huckabee, and other religious conservatives.
Planting Peace is well known for trolling anti-gay groups with large gestures. You might remember they were the ones who painted this rainbow house directly across the street from the Westboro Baptist Church (aka the "god hates fags" a-holes).
