Siskiyou Pass
Siskiyou Pass is a historic mountain pass in the Siskiyou Mountains of Jackson County. It is the most used pass in the U.S. state of Oregon. The Hudson's Bay Company made the Siskiyou Trail over the pass before pioneers traversed it with their wagons, while still later it evolved into a stage road, a railroad line, and a highway route. The name Siskiyou is believed to be derived from Cree, meaning "bob-tailed horse". Wikipedia

I coasted from the summit to the first Ashland exit in the Superbeetle. It got kinda hairy in the corners.

Road
The pass contains a hazardous stretch of the road starting from Milepost 18 of northbound I-5, which has a steep slope of 6%, negotiating a height of 2,000 feet (610 m) in a short road length of 6 miles (9.7 km). The descent along this highway is considered the most dangerous, particularly on foggy nights when visibility is almost next to nothing. In spite of the hazards involved, 13,000 trucks ply this route every day.
