Idaho Thwarts Stoners by Removing 420 Highway Signs
No more fun and games for marijuana enthusiasts in Idaho. The Idaho Transportation Department has had to replace '420' milepost signs with '419.9' signs because stoners keep stealing the 420 signs. Four-twenty is a code-term that refers to marijuana.
Since the legalization of marijuana in Washington and Colorado, those states have also replaced 420 signs with 419.9 signs after several were stolen.
The signs in Idaho are along U.S. Highway 95, just south of Coeur d'Alene.
