I was having overheating issues with my car on the way home last weekend from PatCon and missed my turn. I wound up driving an extra hundred miles out of my way before I could get on another West Bound highway out of Lewiston Idaho.
I ran into this about forty miles inside the Oregon Border on my way home and thought of you so I stopped and snapped a picture. I must have went farther South than I thought!
Best of luck with your PatCon coming up.I am so glad I got to go to this one.
