For reasons lost in the mists of time - or possibly to impared memory function - the number ‘420’ is code for pot. As such, mile markers and other signs bearing that number have become targets for trophy-hunting cannabis enthusiasts.
To combat this expensive annoyance, the State of Idaho has turned to to strategic inaccuracy, labeling their at-risk mile-markers a tenth short to become less appealing to would-be thieves.

I don't believe any states around here would have any 420 mile markers though. Even New York is less than 300 miles long...
