I read an article the other day about people that have done this and I have not been able to get the idea out of my head. I am in the military and have done day long hikes with full battle gear, a rifle, a 50 lb pack and a radio. But this is a whole nother level of endurance. I love hiking and was planing a cross-country trip by car after I get out in 19 months; but this is way better of an idea to me. One of the people I read about in this article was a very old women. It took a year but she finished what she sat out to do. One thing I have learned in the military is that heart goes a lot further then strength.
