BUT DON'T YOU DARE SMOKE A FUCKING CIGARETTE IN AN OPEN-AIR REST AREA ON THE SIDE OF THE INTERSTATE IN IOWA! That shit could kill you!

Yes. The State Legislature of Iowa has so little to do, it took the time to write, debate, and pass a law banning cigarette smoking in rest areas along the Interstates. Because, when they rest 100 yards from some of the busiest Interstate traffic in the country, they don't want to inhale air pollution.
Hell, there was probably more pollution emitted into the air when they manufactured, painted, transported and installed several of these signs in every rest area in the state.
But its the second hand smoke thats gonna get you...
