I plan on thru-hiking 2009, I've been planning/investing in this for a long time, because I'm hard set in doing the ENTIRE hike and therefore I've read/used/and often torture tested a lot of my gear before I leave. After all I've come through with I've kind of come to the assumption that I'm not really going to need much navigation. The name of this site, White Blaze, really describes all the guidance you need, not to mention I'm pretty thoughtful, and rather good at knowing my bearings. If I leave a town I'm going to know how far and what to expect before the next town. I see people complaining about people who don't have maps, etc and want to use theirs... I'm trying to go ultralight but a map is the only thing I can justify leaving at home, so the others won't be a problem. What do you think?
