I am starting the JMT on May 30th, 2013 from Happy Ises - Yosemite. I will be flying out from Boston.

Does anyone have advice on the best approach to take? Easiest to fly to San Fran, Sacremento, Reno, other ?

Once in California, is there public transportation from any of these cities? Bus, train?
Can I rent a car?

Thanks for any info
