Driving from Moab UT to Manitou Springs CO, the weather gradually worsened.  At first it was just snow swirling on the road as cars swooshed past.  Then it was lowering clouds and snow on the rooftops of houses alongside the road.

By the time we got into Vail, it was Winter Twilight.  This picture was taken at 5.55pm as we crested Vail Pass.  Pay no attention to that sign offering 45mph.  Speed: 20mph.
