blast loaned me a book that was called something like "the man who walked through time". It was about a dude who walked the length of the grand canyon 20 or 30 years ao. He had an airplane do drops for him on the way. Its a lot like what you want to do, for the same reasons. At times, he even walked naked, just because he could. A bit weird to some, but in the context of the book, I think it fit in with his mental state. I, however, am not condoning that and would not do it myself. But, I think it would be amusing for you to read it since you are talking about doing the same kinda trip, but in a different location.
Personally, I think you should solicit the help of some well meaning people to set up some food caches for you on the way. Perhaps people from this very forum. I am sure you would get help. I'm not talking about enough help so that you wouldn't have to forage, just, something to look forward to morale wise. Whatever it is that would float your boat. For me, it would probably "one good meal" that I would cook myself. Some meat. Potato. And a bit of chocolate for desert. One meal. But man, it would be cool after 2 weeks of roughing it!
Anyway, I'm a bit jealous, but only in a good way. It would be very nice of you could find a way to share progress with us.
