I honestly think he planned to die, or at least didn't really care enough to spend a lot of time studying or buying proper supplies. He was all for the adventure. He supposedly died from cold and starvation from what I hear (I have yet to see the movie and I haven't read the book but I have read up on him here and there). Before he died, he took a picture of himself holding a sign that said "goodbye", and he was smiling, as if to finally be at peace with knowing he was going home to rest. As for me, I have studied a bit on how to properly field dress different kinds of animals... I have really good supplies that I've spent a year gathering (they are EXPENSIVE and I needed to learn which ones had the best quality for my intended situations).
I myself plan to go off the grid right before the general elections, and more than likely I might die but I don't worry about it. I have planned this for almost two years, and if I die, more than likely it will be by some federal agent ranger dude who is tasked to track possible "dissidents" who fled their state because of martial law (or some other fucked up reason). America is going to collapse, and the powers that be, are going to strengthen their grip on the Constitution and a lot of people are going to die. That is why I bought a handgun and invested in some damn good camping gear while learning woods lore.
I know the main tip in learning woods lore, is going out and trying ideas on for "size" and practice. I haven't been able to do that really because I don't have a car and no REAL friends who are interested in these things. Sad. Whenever I tell people the dire straits and state of affairs our country is in, they usually get bored and start talking about sports or cars or what fast food joint they plan to get their next lunch from. They have no idea... I can't see how more people don't think like me, or why the Hell God hasn't introduced more people like myself to me (I am a really cool kick ass person hehhe) so I assume I am going to do this alone. I feel I am very capable of hacking it in the bush with what I have (knowledge and equipment), but I am sorta nervous because I have had no training at least to hone my knowledge into a working second nature.
In any event, I know I will pray a lot in the wild, because that is the main reason I am going out there... to commune if you will with the universe. Some people might think that is gay sounding, but fuck it. That is the truth. Again, I might die, but fuck it, I will do my best to stay alive and survive but the most important thing I will be doing is praying and developing my relationship with things that are not of this earth. Perhaps, with hope I will develop the eyes to "see" things as they really are, and I just may end up being a forest spirit lol. That is what we all are anyways... just think about that for a second.
Peace.
