“I don’t care how you did it up North” is a popular Southern saying that has been printed on bumper stickers, T-shirts and posters. Southerners have been resentful of people leaving failed states in the North, only to have these newcomers lecture their new neighbors.
 
“I Don’t Give A Damn How You Did It Up North!” was on Florida bumper stickers in 1982. “We Don’t Care How You Did It Up North” was on Texas bumper stickers in 1984.

In regards to the $14 million repair job needed on the new Polk County Courthouse, perhaps its time to change that bumper sticker, “We don’t care how you did it up north,” which I see around here, to “Tell us how you did it up north.”
