Considering a 2016 thru hike since I have some time available next year. However, I have had three knee surgeries and would like to start early and take some 2-3 day breaks to keep it iced (or longer if necessary). I don't have a time frame other than as the weather allows, so I was thinking of driving to Big Bear from SC, left my car there, then when I arrive at big bear, drive to agua dulce, and caught ride back to big bear, the when arrive agua dulce, drive car to Kennedy meadows and catch shuttle back, etc. the benefit to me of this would be having a car for longer breaks, sight seeing, some supplies in car. I realize cost would be more, but would be willing to accept some additional cost. Doable or not?
