I am planning a Yo-Yo hike for 2010, I live in Ga and if im gonna walk to maine i figured I might as well walk back!! Im not using bounce boxes, or mail drops plan on carrying the same equip at the start as I do at end. I have my sleeping gear and other things laid out for just this purpose for example I will be using a 0 degree bag (over kill maybe but I dont like sleeping cold!) and a 11 degree liner so if i get to cold i can use that or in the summer I can use the liner as a summer bag, my base weight minus food will be about 30ish pounds so a 45 pound pack is a good target. Im wondering though how often people yo-yo this thing I have not heard much about it any ideas? oh and Im also leaving Febuary the first. I am ex millitary and have been hiking since I was 15 and will be turning 30 on the trail next year how cool is that!!
