I do like this sort of thing, you just cant make a living with it
My dads farmland was a major camping area for both the Illini & the Kickapoo (& probably some others) after a major storm we can still walk the fields & find all sorts of arrowheads, axes, spears, etc - but nothing like the colection our old neighbor had
He had some spearheads that looked like what you would see in the movie "ZULU" that he had found in the field my dad owns now
When I was young he told me all the good places to look for artifacts, & I didn't pay much attention & now I wish I had
I bought about a five tract of land down here, it was an old pecan orchard that had overgrown terribly. As I was clearing it off, I kept noticing a number of mounds and was thinking INDIAN MOUNDS! I did some checking and discovered that the mounds were horse graves from years and years prior. I do have some 7,000 year old wood though, lol.
