Had a good overnight trip this weekend to Central Oregon.... where it's always dry and dusty. Unless it alters between snow and mud that is so slick I literally drifted around the corners at walking speed. It was difficult to walk in, and looks just like a normal dirt road, but the first 3-4 inches stays on your tires and creates ice-like effects when driving.
