I'm still learning history and admit I used wiki for my statement... but I knew that bronze was the tech to change it all.This also surprised the sugar out of me, because I thought it was the Sumerians who invented bronze. Indeed I was under the impression that iron was in use in southeast Europe since about 1200 BCE, and Romulus and Remus didn't act out their sibling rivalry until 500 BCE...
Speaking of History, that Ben Franklin series has me hooked! What a genius right? A shame if we lose America - that's what I keep thinking. Some people here wishing that our only viable American Vehicle fails... by it's own people no less!
