According to the homeless people I ' ve spoken with , socks is the most common answer . <| sep |> Yup . When we go hiking , my backpack contains a led lamp , a flash light , a 5 meter rope , first aid kit , a swiss army knife , 2 bottles of water , a whistle and a compass . Always prepared . Sometimes depending if there are tall bushes , I also carry a machete , my wife carries a hiking stick with pointy end . And we wear reasonable clothing that wont tear off when a tree branch makes contact with us . Got to be ready ! . we started doing this after we saw 127 Hours . well for her anyways . For me , its after watching Predator 1 . Jungle hiking aint a cake walk ! <| sep |> Out of curiosity what appmethod do you use for book listening ? I manually added one to itunes but it was just a huge seven hour file so tricky to pause and get to the right spot .
