[QUOTE="Warren Okuma, post: 3942280, member: 48436"] My friends brother is a survivalist. He is really good with a bow, which he hunts with during bowhunting season and can make arrows. My uncle hunts boar with only a knife. Oh, and I (not a survivalist) can make gunpowder from scratch (a hobby really). I don't know what kind of survivalists you know... On stuff surviving... It depends. There are paper and leather goods that have survived for 2,000 years. It all depends on the environmental situation. Trash dumps are wonderful places where stuff tends to survive. Some trash dumps are plastic lined, to prevent stuff from getting into the water supplies. These will have the best amount of stuff surviving. Dry climates can preserve a lot, as well as collapsed buildings. Stuff in military arsenals in dun... I mean bunkers can last a very long time, especially the weird airtight ones they don't let my friends near... On tech. Look at an encyclopedia. If just one set survives, technology will recover. If any of my books survive, I can do a full on industrial revolution. I got books on steam engines, industrial theory, and tons of chemistry books. How many books from science/engineering students are out there in the country? Tons I bet. And making ammunition is really easy. Black powder is sulfur charcoal and saltpeter. Sulfur can be extracted from rocks and other sources (provided you know a good rockhound or geologist or get a book, just trial and error), and saltpeter from manure. Making modern ammunition is a bit more complicated. But if there is one chemist (or hobbyist) that survived or science historian all you need is electrical power, and a nitrogen and sulfur source (rocks, manure... a pain in the butt) and either mercury (if you want to do a mercury fulminate) or lead (for lead azide) or potassium perchlorate.
