This thread reminds me of last Sunday, while my mate and I where waking out on a major road (Happy Jacks) in the Australian Alps I came across two persons with rickshaw type carts with about 60kg plus of gear each including several large kitchen cooking pots, they where fascinated by my 8 kg pack and could not believe that we had just spent three days in the bush with such little gear, one guy asks if he could hold my pack to see how heavy it was, after lifting it he pulls out his empty 110 liter pack that weighed nearly as much as my pack, he then went on to explain that for the last thirty years he has carried 35 kg in his pack and that he decided to try using the carts, I advised them to start doing some reading about lightweight gear on the net.
They where in the bottom of a valley and had a 7.5 kilometer pull, which 5.5 kilometers is continuously up hill to get out to their car. We wished them good luck and went on our way.
