I'm 31 years old, and have been hunting with my father my whole life. I, as you can probably tell am no expert either. I have been taught that they always camped above the flood line, but near the water. Also, look for chips of one particular type stone. In my area, I don't know why, but, you will find piles of white quarts chips in one spot, and chips of a different stone , in some instances, 50 foot over. Also , in some fields, old coals can be found every year after the first plowing. Mineral rich land is also good. Red clay is my favorite, because it packs, and things don't sink in the ground as far. Hope this helps you some. Also, remember, they, like you, were human. What do you do?
