Just to add what others are saying, don't forget trade. Pre-Columbian Indians had extensive trade networks to obtain what they could not get locally. Items from the great lakes area have been found all the way to the Gulf Coast and vice versa. Trade in the southern plains extended all the way to South America and the Pacific coast Salt was a great trade item.

Yes i can read quite well but evidently I was too subtle for you. I was illustrating a point. (pointing out a fact) I have seen war first hand. Always worried about the last to die. I now know that they continue dying. So the man who received the distinction of being the last to die was actually not the last. Just because others took longer to die does not mean they did not die in combat on the western front. If you had seen these things you would understand it.

Nope. An ancestor of mine died about 10 years later from complications of mustard gas. That the thing about war, soldiers don't quit dying just because the bullets stop. Buddy of mine died a few years ago from complications of wounds received in Viet Nam.
