If stoners are known for one thing, it's their eye for interior design. So perhaps it's no surprise that mile marker 420 on I-70 through Colorado keeps getting stolen. What else would look better on the wall of your living room?

The marker — which you see above via Google Street View — has actually now been replaced by mile marker 419.99 in the hopes that high 22-year-olds will stick to posters of Bob Marley or whatever. A spokeswoman for the Colorado Department of Transportation calls it "an innovative way for us to keep the sign there."

Naturally, though, it's not the only mile marker Colorado has had to alter recently. At the summit of Cameron Pass just west of Fort Collins, motorists will find themselves driving past mile marker 68.5
