If you family is aware of your plan, then enlist them a bit for some assistance. First, prepare some packages with maps and addresses for a Mail Boxes, Etc. or UPS, they will forward stuff. You carry the ones you need now, receive enws ones as the need for them arises, and send home the used ones, so your weight is less.

Also, it is you putting in a system whereby you'll check in. Want to put your families minds at ease some, give them a way to check in and know where you are and when to expect to hear from you.

Get out this weekend or in the next week and try some things. Put your stuff in a pack, walk into the woods, live there for a couple days, walk out. Any practice is going to help your skills. Bring a book or two while you are there. This will also help you judge your needs, as to what you will need.

Finally, someone up above, Angel, seems to have experience doing what you want to do. I think that's one person who's brain I would seriously be trying to pick.
