LOL! Thanks man, that was hilarious.
The question is intended to be open-ended, to be interpreted by those answering it. But in my own mind, I am thinking at least a week, up to you-don't-even-know-how-long.
Let us assume for the exercise that (for whatever reason) you have to go on foot. I could run through a bunch of hypotheticals, but there's really no point. Assume on foot, only what you can carry, and you're not sure how long you could be out there, but that it will probably be at least a week.
