In case you missed it last week, a truck driver using GPS during an I-70 road closure in Glenwood Canyon tried to navigate his 18-wheeler over Gunnison County Road 3 — which so happens to be the “steep, rocky, four-wheel-drive route” that is used to get to Crystal Mill, the famed Colorado landmark, according to an article Friday in the Aspen Daily News. The truck was on State Highway 133, which goes from Hotchkiss to Carbondale, when the driver turned on CR 3 heading to the town of Marble.
