Yes, it was a bit chilly crossing those hills south of Clatskanie. It was a little unsettling railing those corners on wet roads, and looking down and seeing 30°F on the display!
Fortunately it was only that (non-corrosive) de-icer stuff they spray on the roads. It's good down to 25 °F.
A couple of the pics I took with my phone (8MP). First is of a couple connies floating down the mighty Columbia River. Second is another shot of the Pacific Ocean, at the end of the Oregon Trail.
