For a spectacular and fairly unknown route south from Bishop find your way across the Kern Plateau. From 395 turn right just before the tiny town of Pearsonville. There should be a small sign that says "Kennedy Meadows 25 mi." And I believe the road is called 9 mile canyon. (Sorry I've been going up there so long I don't pay attention any more) That road will take you west to and through Kennedy Meadows, up over Sherman pass and into Kernville. There's some good OHV trails (you might wish you had your 450) but no real lodging, just camping or RV. Once in Kernville the highway will take you out through Bakersfield to the superslab 5. This won't add more than an hour or 2 to your drive. Of course if the weather is turning nasty you'll rethink that route, they don't plow the top of that road!
