We've read alot about the trade that existed between Central and North America in the pre-colonial periods. We know that various nations traded food, furs and worked goods from Costa Rico to the South East United States; we even have some evidence that they used shells as coinage. But there has been large speculation of how much of each society transplanted from one region to the other. According to the archeologist, its quite a bit. Seems that some Mayan ruins have been found in northern Georgia.
That is just bad ass!
