If you intend to live off the land, I suspect that it's going to be a very loooooooong trip. It's hard enough to find enough to eat when you're staying in one place. Finding food while walking 20 or so miles a day could be very tricky.

I would seem to be a better idea to set up a savings account and ask for two or three debit cards. Keep the cards in various places on your person. Since you're not exactly traveling through uncharted territory, just stop at a grocery store when you need supplies. Nearly every place accepts debit cards.

Eat good food regularly. You're going to be using a lot of calories, and you will need to stay in good shape.

It sounds like fun. But I like the motorcycle idea.
