The cost, which we see more as an investment in your future health, for this trip is $6,525.  For that you get all the gear you will need, and all of the food you will eat.  The gear is yours to keep, except for the tent, which you'll only be loaned.  Included in this is your transportation from Fresno to Yosemite National Park, and from Mt. Whitney Portal Store back to Fresno.
