If all they did was change the sign, of course, then it would no longer be accurate. So I assume they have moved it 52.8 feet to the west, but the report doesn't say. Of course I tried to check this using Google Street View, but that imagery is obviously out of date.
So, if you are on your way out there to steal the new one, and I am not suggesting you go out there on I-70 about a mile east of Stratton, just past the fuel tanks on the right, to do that, I'd appreciate it if you would check on the location for me.
(The issue of locational accuracy was my first thought as well.)
