I found another superb, ride, Highway 199, from Crescent City, Calif which run's NE to Grants Pass, Or. About 90 miles.
Then, from Grants Pass, go 15 Mi. S to Medford Or.
From Medford, take the Scinic ride N up to Crater Lake, Volcano, and from there take Oregon 138 back to RoseBurg, Or. ( Do a Google on "Crater Lake" , or check it out at the Wikipedia site )
Or, if you are rideing in Oregon, Any state Highway that cross's E to W or W to E, crossing the Cascade Mt. Range, or, the Coastal Mt. Range is gurenteed to be a good ride.
Any of these routes will be from 60 to 100 miles, of Twisties !!!
And, you will not see any N.Carolina HWP !!
