On another thread, I mentioned how the "best practices", equipment, and outdoor philosophy had changed significantly during my 30-40 years of hiking and camping.
I included this quote from a 1959 book. The quote was regarding proper cleanup procedures following a meal:
"Get rid of the garbage. Burn whatever will burn at one end of the fire. Burn out cans and flatten them. Wash out empty jars. Bury the burned out cans and the washed out jars".
I invite you to go back to your "old" camping/hiking books and magazines and provide us with quotes, photos, or descriptions of the silly (and now outdated) equipment, clothing and "best practices" which were being published as being normal "back in the day".
If you can, try to include the approximate publication date too.
(Your own personal pictures, descriptions and approximate weights of your old hiking and camping equipment might also be fun to share).
