I have permit for 4 people from Kings Canyon Road's End through to Whitney Portal 8/4 - 8/7. Totally psyched about 3 days on the trail. Totally not psyched about logistics.  At this point we have retained East Side Transport to Bishop to rent a car for the return. Ideally I'd find someone exiting the trail at Roads End to drive our car back to the Bay Area. Ideas on how best to manage these logistics, or where I can post to find a hiker / driver that would be up for driving my car?
