The entire continent has been put into a deep freeze, and Oregon has not been spared. I traversed the 80 miles from Portland to the coast recently, and found highway 26 to be covered in ice for most of the route. There were plenty of SUV's in the ditch as I poked along at 35mph.
I made a point of keeping my schedule open enough to allow time to shoot in the snow.
The Coast Range pass is only 1600 feet, and in a typical winter it will get a dusting of snow for a week or two.
