sometimes I go on a primative camping trip, but just for fun, people can pack a virtual pack on excel for a primative camping trip just to see what it might weigh.

First off - actual primative living requires a great deal of skill and a full time investment in hunting and gathering, BUT just for fun, lets pack a primative pack.

Remove everything that didn't exist as a concept 500 years ago. Now if you take the California indian Ishi - he had pots and bowls, fire skills and kit, a knife and flaking knowledge to make tools and arrow heads from rock. He had a cloak of sewn bird wings.

So anyway you could take a pack, tent, down bag, down jacket, leather "cord" for hanging your food, a stone knife, a flint fire starting kit (or any kind), maybe a boda bag for water, light weight foot gear, and otherwise leave everything else at home and go naked, now tell me how heavy that pack would be.

Its snowing here.
