Approximately 148 miles east of Denver on I-70, near the town of Stratton (pop. 669), one used to see mile marker 420 at the side of the road — if it hadn’t been stolen. It seems thieves, presumably marijuana aficionados, cherished the big green-and-white 420 signs.
Tired of constantly replacing the signs, the Colorado Department of Transportation employed a little preventive creativity last year and changed the signs to 419.99.
“So far it’s working,” said Amy Ford, a CDOT spokesperson.
Makes one wonder if they’ll soon be changing the 69 signs to 68.99, as those also tend to disappear.
Update, January 11, 2014: Just found this on PolicyMic:
“Mile 420” is not the only sign desired by sticky-fingered Coloradans. Ford said CDOT placed a “Mile 68.5” sign near the summit of Cameron Pass, west of Fort Collins, after continuous pilfering of the “Mile 69” sign.
