That just doesn't seem possible to me.
I'd like to show you what the bed in my spare bedroom looked like the evening before I left on my Kilimanjaro trip. Everything you see in this picture had to go into one backpack and one duffelbag. The sleeping bag wasn't even in the picture yet, as I picked that up in Tanzania.

Get the picture? I'm not a good packer. I won't admit to too many flaws but that certainly is one I can't get away from. The Kilimanjaro trip really has taught me quite bit though and I'm hoping that when I finally have to pack that camino bag that I will be an expert on what to leave and what to take.
It's going to be a long walk and there are no porters or sherpas, so I'm going to have to be a sensible packer for once in my life. I've started searching all the sites for packing tips and I've come across a wealth of information already.
I am going to have to sift through all the suggestions and make it fit for myself. One thing I've learnt from the Kili trip is to transfer shampoos, creams, toothpaste etc into small containers. It's surprising how long one can make shampoo eg. last if you really have to!
