This is a vision quest, not a vacation, I have to sever all ties with every other person on earth and put my fate in the hands of god.
I am even a little iffy about bringing the dog.
Well have you seen Into The Wild? Sounds like you are wanting to end up like Christopher McCandless AKA Alex Supertramp and starve to death in a bus in the cold, Imagine spraining your ankle 25 miles from anything, if you do and think you could make it you are delusional.
I can understand the desire to be alone, but to do it as you are saying with little to no experience on long journeys in the wilderness it is foolish at best.
