I think most folks would have more fun with a metal detector and a map of Civil and Revolutionary War military camps and battlegrounds, or even just poking around ghost towns or old farmhouses, than looking for pre-Columbian artifacts, up here north of the Rio. It's largely disappointing and if you actually manage to sort-of prove that the broken barely-recognizable spear point you found came from some named group of people circa 800 CE, you'll inevitably find that we know almost nothing about them and that what we do know makes them sound exactly like every other group around that time, since we just don't know much about any of them besides trite generalities.
