You could post this question at groups.yahoo.com/group/johnmuirtrail and you will get many responses. Also see the collection of links and files. My short answer would be: If you are coming in from the West, you could drive the narrow Kaiser Pass Road to Lake Florence (Muir Trail Ranch) or take the bus service Fresno to Lake Edison (offered by Vermillion Valley Resort). You will be at the near-midpoint of the trail (esp at Florence) and can go either North or South. (Edison is about 10 miles north of Florence) You can google all of these or find links at the Yahoo group noted above.
