I'm slowly building a little website that is a directory of survival schools. During this process, it quickly became clear that there are two distinct "schools of thought".

One focuses on primitive skills, oriented somewhat more towards the art and enjoyment of mastering those skills. They tend to pay less attention to what one should carry other than perhaps a knife.

The other is more oriented towards modern techniques and equipment.

Natuarally there is much overlap and either type of school will better equip you to survive.
