Everyone should take a read on
Nessmuk's Woodcraft and Camping
Google it or to to Project Gutenberg. 30 days in the woods was old hat a century ago.

It's not available via project guttenberg but I did find an interesting site called
www.nessmuking.com about Nessmuk.
Seems like ultralight hiking was invented not by modern nuts but by the native Americans. Nessmuk traveled with a 28 lb pack...including his canoe!!!
